Linksys WRT54GS + WRE54G - some questions

Hello,
Thank you for this forum.
I want to buy wireless router Linksys WRT54GS with WRE54G Range Expander for my organisation (small office) and before I have some qustions.
First, how much users WRT54GS with WRE54G can support correctly at the same time work in internet?
WRT54GS (with enable DHCP-server) will be on 3-th floor and WRE54G like repeater signal of WRT54GS will be on 2-th floor.
Usually, all users at the same time work on the 2-th floor (about 5 users), but in theory there will can be 10-15 users maximum (2-th и 3-th floor or only 2-th floor). Will this hardware work propertly without bags or I must see other solutions?

You can even have more than 15 wireless clients connected to your wireless router and range expander at the same time without any lags...

Some questions about my Linksys setup ...

Well first of all I don't know much about wireless network equipment. I just linked them up and it works. However I need to know the following: 1)What is the difference between an access point and a router? I have a router with antennae and that seems to be the access point. It's all I seem to need anyway. 2)I need to extend my range so my cabin which is about 100yds from the house so it can share my network. What kind do I need, i.e. omni-directional? 3)What Dbi should be the least I need? 4)I don't want to spend much money. I've seen those ones with the magnetic base that I can mount on a tin roof. Are they any good? They are cheap ... more suited to my pocket. 5)Some of these antennas specify a reverse polarity connection to the router/access point. I have a Linksys WRT54GS which has detachable antennas. Are the connectors reverse polarity or what? I don't want to risk damaging my router. 6) Is it okay to replace one router antenna with an external antenna and leave the other router antenna in place? 7) In order to extend coverage from the back of the house to the front of the house (the equipment is in the loft against back/front windows) I linked up 2 routers(the second router is a belkin). It seemed to work and I got reception almost to the cabin. The only difference was that I got a choice of 2 networks ... Linksys and Belkin. There didn't seem to be a problem though. Is that okay? Sorry for so many questions but I know that if I get these answered it will help complete my knowledge of these things. I'd appreciate any help you can give me to answer them. Thanks. Well I guess I didn't really expect any help. Everyone seems to be looking for answers, but there's nobody home.

You will need to set the Belkin in "bridged" mode so it can share your internet IP address from the TC/Modem.
I currently run a dual G and N only network using two routers that includes both Apple, Windows computer, ATV and, a net drive. Works like a champ.

Linksys WRT54G LAN Security?

Hi guys, just want to drop some questions around here, hope to have some great responses! Just recently, I've configured Linksys WRT54G as a wireless access point and it's working fine, as well as i enable WEP and MAC filtering security. Now, I've also connected some user through LAN which i doubt to have no security and can easily connect to the internet without MAC filtering or any security authentication. How will i configure this router to filter/restrict the LAN users to access internet? Is it possible? I would appreciate any help from this concern. Thanks, Mike

The WRT54G is designed for home or small office use. Because of this, the wired LAN ports on the router are protected only by "physical security", that is, they are protected because you only allow "trusted" people to come into your home.
Anyone who plugs their computer into a LAN port, will be able to access your network.
If you know the MAC address of a computer, you can use "Access Restrictions" in the router, to deny them access to the Internet. But they will still have access to your LAN.

Help protect my Linksys WRT54G from the "curl" command which bypasses my security settings

It's way too easy to break into my Linksys WRT54G router!
Do you have firmware that will fix this vulnerability?
Instantly bypassing the administrator password, my fifteen-year old
neighbor broke into my Linksys WRT54G router (firmware revision v1.0.0.6)
in ten seconds simply by sending this one "curl" command to it via the
Internet from his home next door!
c:\> curl -d "SecurityMode=0&layout=en" http://192.168.0.1/Security.tri
This kid was kind enough to knock on my door today to tell me to fix it.
I invited him in, and from inside my own house, he showed me the Linksys
WRT54G command above which immediately disabled all my wireless security
WITHOUT him having to enter any password!
He showed me how to disable remote administration but he said the
vulnerability still exists until I get a new router. I can't believe
everyone with a Linksys WRT54G router is throwing it in the garbage.
Where/how can I find a firmware update that protects me from this curl
vulnerability?

To protect your router:
* disable remote management.
* enable WPA2 or WPA with a strong preshared key on the router.
That is essentially all you must do. This protects against the curl problem (from the outside). The benefits of the rest varies:
* set a strong, hard to guess password on the router.
That's always a good idea to prevent some guest coming over, plugging into your network and modifying the router. For that to be relevant the person either needs physical access to your wired LAN or the WPA key.
* disable UPnP
Good idea if you are worried you could install some malware on your computer. UPnP allows to set port forwardings for incoming connections from the internet. It allows a computer to automatically setup the forwarding to make a server accessible in the internet. You'll often need this for gaming. But it obviously can be exploited by malware.
* access server to https instead of http
With WPA in place on the wireless this is only really necessary if you worry about someone gaining physical access to your router. https protects the password transmission to the router. But then, if someone gains physical access to my router I think the protection of my password would be the least of my problems.
* disable wireless access to the router configuration
For this to be effective with WPA in place would require the attacker to crack WPA to get into your WLAN. WPA is considered secure at this time. Anyone cracking WPA with a strong key must have a lot of computing power and a lot of knowledge. I don't know if this setting would really prevent that attacker of gaining full access to the router. This setting may be useful if you have an occasional guest to which you grant wireless access to the internet...
* changing the default IP address from 192.168.1.1 to something else and turning off the DHCP server on the router
With the DHCP server in place changing the IP address is no mean of protection because the DHCP server assigns a correct IP address in your LAN. You have to setup static IP addresses on all computers and devices. However, if someone gained access to your LAN (wireless or wired) all you have to do is wait and listen to the LAN traffic. It usually takes a few seconds until some noisy windows computer will broadcast a message and you have picked up the IP addresses in the LAN
Some more things often mentioned with questionable benefits:
* turn off SSID broadcast
Supposed to make the WLAN "invisible". O.K. It does make it harder for the average Joe to check what WLANs are in the neighborhood and which channels they use to optimize the choice of channels and limit interference. It does also prevent accidental connection attempts. However, with WPA/WPA2 in place the WLAN is protected anyway. Anyone, who really wants to know if there is a network can scan with a wireless card in monitor mode. The SSID is transmitted unencrypted. Plus in average it requires more times and more power (on laptops) to connect to the network as the wireless card must actively try to connect to each configured WLAN on the computer to find out if the network is there or not. With SSID broadcast it simply scans for broadcasts and then knows the network is there...
* wireless MAC address filtering
Supposed to limit the computers which can connect to the WLAN. Only computers with the MAC address on the list can connect. Again, this only prevents accidental connection attempts. MAC addresses are transmitted unencrypted. It is easy to pick them up with a wireless scanner. Thus, for anyone who knew how to crack WPA the MAC address filter list will be the least of problems. Most wireless cards can be configured with any MAC address you like. But the list increases the amount of effort for you to add another wireless computer to your WLAN as you always have to remember to set it up correctly...

Linksys wrt54g- MAC cloning

I just bought a Linksys wireless router and have researched a few threads regarding compatibility. I have not installed it yet since i want to make sure i know how to do it.
Questions;
some threads have a reference to not being able to access the web set-up via Safari. is this true?
Nobody mentions MAC cloning or MAC filtering settings in the set-up threads, yet the linksys manual says "some ISP's require a unique address". Do I just try to see if I need to MAC clone the address once I can't connect? What are the right steps?
what is the correct setting for MAC filtering?
system: 10.3.9
Mac: G5; dual 1.8Ghz
Router: wrt54g
Cable modem: scientific Atlanata; ISP: Charter
NEtwork: home; two macs (one wireless, the other hardwired) and one wireless PC, HP laptop

In this case its the same answer I'm afraid
An iMac has different drivers than a MacBook Pro (One is a desktop computer and one is a portable computer.) If they were identical models and builds then you can do a direct "clone" or image of a system from one to the other. However when the two systems in question are two different physical models, imaging is not a good idea. It might work, but you will almost certainly encounter some kind of functionality issues down the road and have to completely Erase and Install the Macbook Pro using it's original install disks to restore the missing driver set.
Read the article I referenced on Migration Assistant. You can use a direct cable connection or a network connection to transfer your data (Or use an external hard drive and follow this article to use Disk Utility to image your old system to the drive http://support.apple.com/kb/HT1553).

How to hook up a Linksys WRT54G to Motorola NVG589. PLEASE HELP!

Hello, I have recently switched over to AT&T Uverse and I am loving it. One thing I miss is having extra ethernet ports to plug in my desktop computer and my Xbox 360. When the Uverse technician came in, he installed a Motorola NVG589 modem that also has a built in wireless router. He also installed a VAP2500 as a receiver for 2 wireless TV boxes. The VAP2500 plugs into the back of the Motorola NVG589. 3 other TV boxes are plugged into the back as well. My dilemma is the fact that all of the ports are being taken up. I need at least 2 more ethernet ports free so I can hook up my Xbox 360 (my model doesn't have built in wifi) and my desktop computer as well. I told the technician this when he installed the system and he told me to go on ebay and buy 2 cheap splitters and split 2 TV boxes that are coming into the NVG589. I did so. It didn't work out. I called up AT&T and the guy over the phone said that was the worst thing I could've done. He told be I should buy an ethernet switch. I had my Linksys WRT54G (Version 6) router laying around at the time and realized that it had a built in ethernet switch. I want to get this to also function as another Wifi hotspot because I have an old PowerMac G4 downstairs that won't connect to the NVG589 for some reason (it says connection timeout). I am guessing that the wifi card in the system may be too old to connect to the modern NVG589. So, I need the 2 extra ethernet ports and another Wifi hotspot from this setup. I have tried multiple things to get this to work. The closest way I could get it to work was when I plugged an ethernet cable from the LAN port on the WRT54G to port on the back of the NVG589. I then plugged the TV box ethernet cable I had to disconnect into the second LAN port on the WRT54G as well as plugging my Xbox 360 into the 3rd LAN port and my computer into the 4th LAN port. This worked great for the TV box and the Xbox 360. However, the computer's ethernet connection ran very slow and the WIfi from the WRT54G was very slow as well. The Wifi from the NVG589 was slow too. I unhooked that setup and put it back to what it was beforehand. Is there anyone that knows of a flawless way of setting this up? Any articles someone can link me to? I've heard of bridging the NVG589...would that help me? How exactly would I do that? Please HELP. I have attached pics. On the back of the NVG589 - green ethernet is the DSL cable, both white ethernet cables along with the black one are TV boxes and the yellow ethernet cable is the VAP 2500. Thanks!

Ya, the install tech must have been sleeping or texting or something during training.... or it's possible he misunderstood you and thought your were talking about needing extra phone ports, which could be accomplished with simple splitters. You were almost where you needed to be with your setup, you just missed some steps. Connect your wired computer only to one of the Linksys' LAN port. With the Linksys powered up press and hold the reset button for 15 seconds (will need toothpick or unfolded paperclip). This will perform a "factory" reset. When the Linksys is fully rebooted, log in to the Linksys. Do not configure the "Internet Connection Type" on the Linksys. Navigate to the "Wireless" section on the Linksys and configure the wireless. Do not use the same SSID (wireless network name) that the NVG589 uses. Save changes. Navigate to the "LAN" configuration on the Linksys and set the routers address to 192.168.1.1 and disable the DHCP Server. Save changes. This step will kick you out of the router. Power down your computer and the Linksys, run an Ethernet cable from a LAN port on the NVG589 to a LAN port on the Linksys, then power up the Linksys, and when it's fully rebooted, power up your computer. You should be good to go at this point. You will want to individually configure your wireless devices to use either the wireless network from the NVG or the wireless network from the Linksys. Otherwise they make keep jumping back and forth between the two, which will degrade performance for that device. You may still notice a slight to moderate performance drop for the wireless on both the NVG and the Linksys because they will be competing for the same wireless airspace along with the VAP2500.

MacBook Pro can't obtain IP address from Linksys WRT54G v2 router

I believe I am having the issue described in the article below:
http://docs.info.apple.com/article.html?artnum=304817
In a nutshell, AirPort seems to be seeing the wireless router just fine, but internet connect is a no go. The router is a Linksys WRT54G v2, which should - SHOULD - work w/ my brand new MBP C2D 17", based on the reports I have seen in other threads here.
In the Network Status tab of the network pref pane, the message is: "Airport is connected to the network linksys. Airport has a self-assigned IP address and may not be able to connect to the Internet." This is in line with the Apple tech doc cited at the link above.
I am starting a new thread on this because, unlike many of the other folks who are having problems connecting wirelessly, my actual wireless connection seems to be rock solid (AirPort connects to the Linksys instantly, and shows up as full strength with no apparent dropouts). The problem seems to be with the IP address, as the MBP can't/won't pickup anything other than its self assigned IP when connecting.
Here are the things I have tried so far (most of which are probably irrelevant as it turns out, b/c the actual wireless connection has been fine - just not the TCP/IP stuff):
1. Updated to latest firmware in router.
2. Tried switching to different wireless channel (ch. 11 in this case, based on reports in other threads).
3. In Linksys settings, changed beacon interval to 50 and lowered packet thresholds as described in another post (can't find the link right now).
4. Formatted and re-installed OSX onto the MBP. Did NOT use Migration Assistant this time (since others were apparently having problems due to out of date prefs and PowerPC related items copied over from older machines).
5. Updated to latest version of OSX Tiger (10.4.8 with all patches installed) using a wired Ethernet connection to the internet.
6. Downloaded and installed the AirPort Update patch 2006-002 located at:
http://www.apple.com/support/downloads/airportupdate2006002.html
7. Repeatedly trashed all AirPort-related keychain items and the SystemPreferences folder in Root/Library/Preferences.
8. Repeatedly trashed and re-created a new wireless location using Network Assistant.
9. Salaam thrice towards Cupertino, wave rubber chicken and bathe self in pigs' blood while humming a continuous medley of Mac startup chimes from the last two decades.
Just kidding about #9, mostly.
I am starting a new thread about this because I believe my issue is OS related. The AirPort hardware seems to have a a full-strength and non-intermittent connection to the Linksys router. The problem appears to be w/ the (in)ability of OSX to negotiate an IP lease with the Linksys box.
I am posting this to the Linksys forum as well, but do not believe this to be a Linksys issue. I have two other PowerPC-based Mac laptops in my office, both of which connect flawlessly to the Linksys. (I'm typing this from one of them.) In fact, I have torture tested my new MBP with several other wireless routers with the same result - MBP will not connect, while both of the PowerBooks work like a charm with the other routers in question. Therefore, it surely seems to me like the common denominator here is definitely the MBP and not the router. I realize that in the support doc at the top of this post, Apple claims it is the responsibility of the router manufacturer, but I just cannot buy that line - based on the fact that EVERY OTHER LAPTOP that I own works great with the Linksys except for my shiny new MBP.
Beautiful machine otherwise and I really can't wait to get it working, but this is a SERIOUS pain in the you know what.
At any rate, if anyone has any ideas as to what to try next, I would love to hear about it. I will be calling AppleCare again first thing tomorrow morning, but it always seems the users are better informed than the Apple guys.
Thanks in advance for any suggestions.

if other computers connect to the router just fine , doesn't seem to me a router problem then .. the only thing i can think is to try connecting to a different network and see whether it does any good to u...can't help much if it's an OS related issue...

Can no longer connect to internet wirelessly with Linksys WRT54G...

Hi, all...
I'm at my father-in-law's house. His home network setup is as follows:
* Compaq desktop connected via Ethernet cable to
* Linksys WRT54G, v3 (IP 192.168.2.1) connected via Ethernet cable to
* Westell DSL modem provided by SouthEast Telephone (his ISP - IP 192.168.1.1)
I set this equipment up for him about 18 months ago. His Compaq desktop connects perfectly to the internet, using the setup I described above, which I set up for him about 18 months ago. I *used* to be able to connect to the internet wirelessly (with both my IBM ThinkPad and my MacBook; my bro-in-law *used* to be able to connect to the internet wireless (with his Dell laptop).
For reasons we don't yet understand, neither of us can connect wirelessly to the internet any longer. I have called Linksys, posted to their board, and read other threads here, so I am aware that MacBooks have some issues with Linksys routers. I'm getting ready to phone my father-in-law's ISP, to see if they can help.
But... I don't understand why this used to work, but doesn't any longer. I would be very grateful for any help any of you great folks could provide, and I will gladly post here any detailed info on the setup that might be of help!
Many thanks,
Bill J.

Thanks for your reply.
Actually the Linksys 2Wire modem works fine in OSX and when connecting via a Compaq PC I also have in the house. It is just on the MacBook running XP that it fails to "connect". XP see's the network but cannot connect.
Also, I downloaded again bootcamp and created a fresh driver CD, reinstalled the driver and received the same error: 1706 No valid source could be found for product Macintoish Drivers foir Windows XP.msi.
I looked at the directory on the CD and it appears that there are no driver files, only documentation.
I called Apple, got no help, called Microsoft, spent 1.5 hours talking to them
they were no help either.
I sent a messge to the bootcamp beta mail address informing them that it seems the drivers are not being downloaded with bootcamp.
Thx again.

Use airport express to extend network from linksys wrt54g

Hello all, I'm having no luck here, and hope you can help me. I am running a MacBook Pro, 2.16 GHz, Intel Core 2 Duo, 3 Gigs ram, OS X 10.6.8.I am at work, trying to use a newly purchased AirPort Express to extend the signal from the back office, which has a Linksys WRT54G router. I updated the router's firmware to 1.02.8, build 001, dated 8.5.09. I have tried numerous times to configure the AE using AirPort Utility, and always wind up with an error message, "An error occurred while updating the configuration. Make sure your Apple Wi-Fi base station is plugged in and in range of your computer or connected via Ethernet and try again. (-6753)" During the configuration process, I am asked what I want to do with AE, I have tried both "create a new wireless network," and "I want AE to join my current network," with no success. Any comments will be appreciated.

The Linksys WRT54G and WRT54GS (through version 4 only for both models) were said to be compatible with Apple's WDS settings.
Perhaps this article may offer some clues, but it is doubtful that you will be able to make this work with the particular version of Linksys router that you have.

Insufficient Bandwidth Linksys WRT54G 2.2

IChat 3.01 works fine if I connect my computer directly to my Comcast cable modem. When connected through the WRT54G I can text chat but audio chat attempts produce the dreaded "insufficient bandwidth" message. I updated the Linksys to v4.20.7. I have tried to open ports as listed in some of the other posts on this problem. I have selected Upnp enable, and Upnp disable. I have selected DHCP disable, and enable. I have reinstalled the 10.4.2 update. I have repaired permissions. In short, I have tried to utilize every fix detailed in the hundreds of messages offering fixes. Since iChat works fine without the Linksys in the mix, I am inevitably led back to the idea that somewhere I have a mistake in my Linksys setup. Has anyone got a setup guide for v4.20.7 firmware of the Linksys WRT54G that will help me step through each and every setting required to get this thing working? Or is this device just not going to ever work with iChat? Thanks in advance for your help.

I have the WRT54G (Ver 4.0/4.20.7 firmware). I have mine configured with UPnP only which opens the following ports: 1024 to 5000 Both TCP and UDP.
Try configuring it only with UPnP enabled(Take out all of the port forwarding and port openings, Unplug your modem, router, and mac and then plug them in in this order: Modem (then wait a minutes or two),router (then wait a few seconds), and then your mac and give that a go.
Then try testing with a known working screen account. (My screen name is in my profile if you want to test with me)
I've noticed the WRT54G isn't real good releasing ports from UPnP without rebooting.
That's how I got my WRT54G working and I can now chat with both Mac and PC's.
Hope this helps!
P.S. I have my mac firewall off.

Need Help Streaming Video From Web Server Built Into Application - Linksys WRT54g Router

Very much appreciate any help getting streaming video feed from web server built into video application to work properly using port forwarding on my Linksys WRT54g wireless router.
Here is the situation:
My PC is connected to the internet via a Linksys WRT54g wireless router.
The Windows XP Pro SP2 firewall is enabled, with a firewall exception established for the video camera application.
On the router, forwarding of port 80 is enabled for the LAN IP address of the PC running the video application with an embedded web server, and the web server in the video camera application is also set to use port 80.
I have a free DYNDNS account and also run the DYNDNS updater program on the PC running the video application with embedded web server. According to the DYNDNS web site and the DYNDNS updater program, the IP address assigned to the machine running the video application with embedded web server is set correctly in my dyndns account.
When I open a browser (Explorer or Firefox) on the PC running the video camera application with embedded web server, I am able to connect to the video application's web server by going to the dyndns address linked to the machine running the video application. The video application's web server is set to use the dyndns address. That's the good news. The bad news is that I can't connect to the video application's web server from any machine that connects to the internet that uses a router other than the router used by the PC running the video application. I am only able to connect to the streaming video from the application's web server only on machines that connect to the internet using the same (home) router used by the PC that is running the video application.
Since I am able to connect to the video app's embedded web server successfully on the machine running the video application, it seems that at least something about the current port forwarding settings is correct. For example, if I uncheck 'enable' for forwarding of port 80 on the router settings page, I am no longer able to connect to the video app's web server when I try to do so in a browser running on the machine running the video app. When I re-enable port 80 forwarding on the router, I am again able to connect to the web server of the video application on the machine running the video app. I thought that by enabling forwarding of port 80 on the router and associating that port with the LAN IP of the machine running the video application, it would be possible to connect to the streaming video of the video app's embedded web server from ANY machine connected to the internet, but that is not the case. There must be some other router settings to update/change in order to get the port forwarding working to enable a successful connection to the video web server, but I am stumped. Very grateful for any suggestions as to how to get this working properly.
Thanks in advance...

The firewall log can be configured on the third tab in the window for the firewall settings, where you can turn the firewall on and off completely.
From your tests, though, it does not seem to be the firewall. However, to be sure, it would be good to check the log. It will help to eliminate the firewall as the culprit and you may find it handy in the future, too. ;-) Just don't forget to turn the log off again after you are done because it may cause some performance penalty on your system while on.
From what you write, it seems as if I should give a little networking background on the ip addresses you'll see. Your setup is (or should be) a modem connected to the WAN/Internet port of the WRT. The computer is connected into a LAN port of the WRT.
Your router has two IP addresses (that's what makes it a router): a WAN address and a LAN address. The WAN address is the address assigned by the ISP. It is a normal internet IP address. Everyone is able to send packets to this IP address. The WAN address is the one reported by whatismyipaddress.com, it should be listed in the dyndns record and it is the address that your router shows on the Status page. It's the public IP address of your router. Dyndns maps your dyndns.org name to that IP address.
Your router also has an IP address on the LAN side. You can configure it to be whatever you want. The default is 192.168.1.1 with netmask 255.255.255.0 and it is better to leave it like that or at least inside the network 192.168.*.*. 192.168 is a special, reserved IP address range for private networks. Basically, routers in the internet are not supposed to forward addresses in this range. That makes them suitable for private LANs as the packets never can get anywhere. Most people using Linksys routers have there LAN in 192.168.1.*.
The router acts as gateway, which means it forwards packets from PCs in the LAN to the internet and back. As all your PCs in your LAN share a single WAN IP address, the gateway does address translation (NAT). This works only in one direction: from the inside to the outside. The router remembers when a PC in your LAN sends something out and accepts the responses in and sending them back to the PC. If something comes in from the internet which cannot be associated with a ongoing communication the packet is dropped unless you use port forwarding.
All computers in your LAN either have a static IP address assigned or use DHCP to get it automatically. The router has a DHCP server as well which gives out IP address from 192.168.1.100-149 if not changed. With a router with default settings static IP addresses can be in the range of 192.168.1.2-99 and 150-254.
ipconfig /all reports your IP address in your LAN, i.e. an address 192.168.1.*. The gateway in this output should be 192.168.1.1 which is your router. And packet no in the LAN address range 192.168.1.* is send to the router which forwards the packets into the internet.
An address 192.168.1.* should not appear as internet address in the Status page of the router nor should it appear at dyndns.
Port forwarding is used to operate a server in the LAN. By default, a server in the LAN cannot be reached from the internet. You have to configure port forwarding for this. You configure that traffic bound for a specific port (e.g. TCP port 80 for http) on your WAN IP address is forwarded to the same port on a specific LAN IP address. If your server runs on 192.168.1.50 than traffic to your WAN IP address port 80 is forwarded to 192.168.1.50 port 80. That way your HTTP server can be reached from the internet. As you can only configure a fixed IP address in port forwarding it is recommended that the server uses a static IP address and not DHCP as in the latter case the IP address may change over time...
O.K. so much for networking. I hope that makes things a little clearer and you can verify that your setup is how it is intended to be.
I suggest the following: on the router's security page there is an option to block WAN requests. Remove the check if it is set (meaning: do not block). After you did that change you should be able to ping your WAN address (e.g. ping xxxx.dyndns.org) from the internet. That way we know that it is on the correct address.
Also on the Administration page make sure that remote management is disabled (should be like that per default) or that the management port is NOT 80 but for example 8080. What is your your UPnP settings on the same page?
O.K. that should be enough for the moment...

Cant connect IPOD to linksys WRT54G router

Hi, i have a LINKSYS WRT54G router .. i bought an apple ipod touch recently and i am unable to connect it to my wifi network. My ipod detects the wifi network but when i select it , it asks for password. now i dont know which password is this bcoz everytime i poer on my computer or laptop i never type a password b4 accessing internet.. it is auto connected. i know the admin password for my router but that is denied by ipod to connect to internet. Is there any other password we have to give for connecting deveices through LINKSYS or some changes i need to do in my connection ? PLzz help plzzzzzzzzzzzzz

you can go to this link for instructions on how to get your wireless password:

Using Linksys WRT54G as a wired network extender with Time Capsule

I have been using the WRT54G as my primary home router with an Airport Express attached to it via Ethernet cable at the opposite end of the house to extend my network. I have recently purchased a Time Capsule, which I plan to make my primary router, and I would like to use the Linksys as the extender and free up the AE to take to my office for music streaming. Is this a doable solution, and is the Linksys difficult to set up for this purpose? The AE currently uses the same network name and password as the Linksys and is a seamless extension of my network. I'd like for the new configuration to be just as seamless.

Welcome to the discussions, Hookshot!
I would like to use the Linksys as the extender
That is doable if you connect the Linksys to the Time Capsule using the ethernet cable and configure the Linksys in "bridge mode" to use the exact same wireless network name, security settings and password as the Time Capsule network.
and is the Linksys difficult to set up for this purpose?
You might want to post on the Linksys forum for that question as we would not have that type of specific info on the Time Capsule forum.
and free up the AE to take to my office for music streaming
The Express would be configured to "join" a wireless network for this. The Express will pick up the strongest signal from either the Time Capsule or Linksys, depending on where they are located in relation to each other.
I'd like for the new configuration to be just as seamless.
It will be if you use the exact same wireless network name, security and password on the Time Capsule and Linksys devices.

I have a Linksys WRT54G wireless router that has a MAC address

A month ago, I could print from my PC and my Mac to my Epson printer over my Linksys WRT54G wireless network. Now, for some reason, I cannot connect and print from either computer. An Epson tech asked me to check the MAC address of the Mac and the printer to see if they were the same. They were not. He then opined that might be why I couldn't print.
I don't know what changed a month or so ago or why it changed. I have not done anything to change the MAC address on either the MAC or the printer.
The Epson guy said the problem might be fixed by adding my printer's MAC address to my router's MAC address. Something about "enabling MAC address filtering". Then he told me that was an issue to pursue with my router manufacturer. Naturally.
Speaking of that problem...someone else had it, too...another technician at another site wrote: "...by default, routers don't come with mac address filtering enabled...and if that's the case....then adding the printer's MAC will not solve any issue that you may be having..."
So, three qustions:
(1) Can I add my Epson Workforce 545 printer's MAC address to my Linksys router? Is that possible?
(2) If I can do it, how do I do it? I saw no "add" or "edit" functions on the Linksys WRT54G Status Page.
(3) What causes MAC address mismatching to happen? What is unstable in that assembly?
Solved!
Go to Solution.

Mac addresses with different devices will differ. No two devices will have the same mac address. this is also called the hardware address. This is designed so that it will serve as a unique identifier of your devices in the network which you can check thru the router. Now it is possible that wireless mac filter might be blocking it from connecting to the network. But it would be best to check as well and make sure that the printer is connected to your network and has the same ip address segment as your router.
How to check if mac filter is enabled:
Setting up wireless MAC Filtering to permit users to connect to the wireless network on your Linksys...
Setting up wireless MAC Filtering to prevent users from connecting to the wireless network on your L...

Link 2 Linksys WRT54G together

Our office has 2 connections to the internet. Each connection comes into our building through a Linksys WRT54G router. I like to connect the routers together through their ethernet ports so that we can share resources such as printers and etc. Should I config each router such that they are actually on the same network? For example:
Router 1:
Router IP 192.168.1.1
DHCP serves 192.168.1.100-150
Router 2:
Router IP 192.168.1.2
DHCP serves 192.168.151-200
Or do I have to configure each router to be on its own network and set up some form of routing between the routers?

There are two ways to cascade a Linksys router to another Linksys router:
Connecting one of the Ethernet ports of the second Linksys router to one of the Ethernet ports of the main Linksys router.
Connecting one of the Ethernet ports of the second Linksys router to the Internet port of the main Linksys router.
