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...

  • 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...

  • WRT54G Wired Security?

    Ok, I have searched throught the posts but nothing really dwells on my desired information.
    Here is the situation.
    I am in Iraq and I recently purchased and installed a Satellite Internet system to a tune of $3222 for hardware and I am paying $450 a month for 512/256.  All systems have a total Bandwidth cap unless you pay an extreme amount of money.  The system came with 5 IP's.  The Modem is an iDirect 3000 series with one Lan port.  I have this connected to a Linksys WRT54G router.  Currently I have the single IP set in the router and enable DCHP so all user computers have automatic IP.  For wireless, I am using MAC filter and security with SSID not being broadcast.
    Problem is, a few people have access to the office when I am not around.  Normally I don't mind them using a drop to check mail and such, but I am worried many of these soldiers are downloading large amounts of data and are going to exceed my total bandwidth cap, which will effect my work requirements, I am a contractor.
    At one time, I had a Belkin Router, which allowed MAC filtering for wired connections as well, I do not see this on the WRT54G, does it exist?
    I guess I can manually assign IP addresses to the few allowed to connect, but I like the simplicity of the MAC filtering.  Any ideas?
    Thanks,
     Vincent

    Well logon to router’s setup page go to “Access Restrictions” >> select policy no. and create a policy to allow connection >> click on “edit list of PCs” and specify MAC address no of certain pc’s which you want to allow internet connection and save settings…

  • AirPort Express drop-out / skips -- Windows XPSP2 w/ Linksys WRT54GS router

    Hello,
    I'm having some skipping / drop-out issues when streaming music from a Windows XPSP2 fileserver, which runs iTunes 7.3.2.6, to my AirPort Express. I've long suspected my LinkSys WRT54GS router. Here are some things I've tried:
    * tried enabling logging on my AirPort Express unit, (I actually installed a Windows SysLog client and ensured it was working) but it reveals no useful information after a skip -- just debug logging. No change.
    * changed the wireless channel from 6 to 11. No change.
    * Do not have wireless security enabled (just don't broadcast ESS ID). No change.
    * Latest firmware on router, AirPort Express, and iTunes. No change.
    * All other wireless devices in the house turned off. No change.
    I'm seriously considering buying a new wireless DSL router to see if it makes the problem go away (any suggestions to makes or models appreciated). Unfortunately my WRT54GS is not one of the routers that supports reflashing with a third-party firmware, or I would have done this eons ago.
    Another thing I am not sure how to test is the signal strength that the Airport Express gets from my LinkSys WRT54GS router. I've not been able to figure out how to get this information, and I also do not know what are considered good / not-good strengths. Any help here would be great.
    Here are some details.
    AirPort Express with Firmware 6.3, communicating wirelessly over Channel 11 to my LinkSys WRT54GS router with firmware 1.52.0, into which my Windows XPSP2 fileserver is physically connected with CAT5 cable. The music files are served up on a Maxtor DiamondMax 10 7200 rpm 300GB Serial ATA-150 Hard Drive.
    I've really tried everything I can think of, and I still get skipping.
    Specifically, music will play fine for 45 minutes, or 5 minutes, or an hour; then, the music will suddenly stop. The AirPort Express will continue to have its green LED on, though. The music will resume 1-10 seconds later. This skipping will happen periodically for a 1-2 minute period, usually 2-3 times per minute, go away for an indeterminate amount of time; or, it might persist until I get tired and turn off my stereo. There is no pattern as to time of day so I don't suspect neighborly interference.
    Other things in the house are an older 802.11b laptop, 5.8GHz phone, brand new microwave, and a few dozen Palm and Windows PDAs that all have their WiFis disabled, where appropriate.
    Any suggestions or ideas would be fantastic. This has been a problem for a couple of years now which I have systematically (though unsuccessfully) tried to solve.
    Thanks,
    -Jeff

    I haven't yet budgeted to buy a different router, but I'll respond when I do as to whether this was the fix or not.
    Just an observation ... in your case, the music streams wirelessly from your laptop to your router, and then wirelessly again from the router to your Airport. That's 2 wireless paths it must go. In my case, music streams directly to my router with a LAN cable; then, wirelessly from my router to the airport. So that's only 1 wireless path, and even still I am experiencing problems.

  • 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!

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.

  • How do I configure my Airport to work well with a Linksys WRT54G?

    I have DSL Extreme coming into my house in bridge mode. (Don't know the specifics, but they said that's how it has to work.) I had my Airport Extreme connected to the modem, sending out a nice wireless signal.
    I was given a Linksys WRT54G Ver. 6 wireless router, and I thought I'd use it as the main router connected the modem. I also want to use it as a wireless access point for one half the house for b/g devices AND I also want to set up the Airport Extreme as another wired access point for the other half of the house for n devices.
    So, I set up the Linksys as the main router sending out a wireless signal on channel 1 for b/g devices. I connected the WAN port of the Airport to one of the open LAN ports on the Linksys, changed the Airport to Bridge mode, and set up a new wirelss network to broadcast on a different channel. Unfortunately, this isn't working. Only the Linksys wireless is working properly, i.e. connected to the internet. The Airport broadcasts the wireless signal, but it isn't connecting to the internet.
    I've tried changing the IP address of the Airport to one that falls within the range of the Linksys (192.168.1.x) and making sure that the subnet of the Airport is identical to the Linksys. I've also added the DNS servers, although I'm not sure why the Airport Admin Utility asked for this. Regardless, nothing works. I'll get a green light, but there's no connectivity to the internet.
    I've also tried connecting to a LAN port and not the WAN port on the Airport. No joy there.
    I've read through numerous threads, and they all seem to indicate that my original set up should work. I've upgraded my Linksys firmware, to no avail. I don't want the Airport to be a repeater as there is a reduction in speed. I want to have two separate wireless access points.
    Thanks in advance for any and all help.

    Ok, I got you. Prior to the introduction of the simultaneous dual-band routers, the only way to mimic them was exactly what you are trying to do. Connect two routers by Ethernet and create separate wireless networks to allow clients to connect to either as appropriate.
    You are also correct that the upstream router (Linksys) should have both NAT & DHCP enabled and that the downstream router (AirPort) be configured as a bridge. The only recommendation is to set the AirPort's static Private IP address to one just outside of the Linksys' DHCP server range instead of inside it to prevent the same IP address being handed out to multiple clients.
    You could do this a number of ways, but the simplest would be to use the Configure IPv4 = Manually option on the TCP/IP tab within the AirPort Utility. Use the LAN-side IP address of the Linksys for the Router Address, and the appropriate DNS server addresses (either your ISP's or a service like OpenDNS). The Domain Name field can be left blank.
    Since the AirPort is in bridge mode, it really doesn't matter which Ethernet port (WAN or LAN) you connect the Linksys to, but for consistency, I would recommend the WAN (circle-of-dots) port.

  • Linksys WRT54GS and AX WDS with WPA

    I have researched everything in these forums and I thank all for their hard work. Am I to conclude that if I want to use the AX as a bridge (WDS) that I can only use WEP encryption? I tried following the instructions with WPA and when I plug the AX back in, after the cycle time it goes green for about 5-7 seconds then starts to flash yellow. What are my options?
    If I by the new Airport 802.11n will it help? I know I won't be able to access the n speed since I am only core duo and not core2 Duo but I really want to make this bridge happen on a secure network. Any other options? I am trying to provide secure internet access for my home entertainment system (Kenwood) over a wireless network since there is no RJ45 plug nearby.

  • AirPort to Linksys WRT54G w/WPA

    So it's the holidays and I'm at my mother's house, where someone set up a wireless network through a Linksys WRT54G. Through her computer we printed up the router's security info, but the network seems to be carefully hidden--nothing shows up under the AirPort drop-down menu. When I use Internet Connect to try and log in manually, the available fields don't seem to match so that I'm not ever sure I'm doing it right.
    Linksys, for example, uses a "WPA Pre-Shared Key" but my PowerBook's Internet Connect menu only offers WPA Personal or WPA Enterprise. Which one to use? Neither seems to be working--WPA Personal seems to get closer than any other method, recognizing the network but not connecting.
    Does all this stuff about TKIP and algorithms have anything to do with anything?
    Thanks for any help.

  • Using Linksys WRT54G as an AP

    I recently moved into a new home with a roomate and our DSL box is 4 port wireless router. One desktop is hardlined into that, my laptop has no problems keeping a good connection to it wireless, but my PC in the back bedroom frequently drops connection... and I'm getting really tired of /release and /renew. I have a Linksys WRT54G v6 wireless router and was wondering if there is someway I can use this product to boost my signal to the DSL box. I'm kind of computer savvy but this is stumping me. I hardlined the DSL box into the Linksys from one lan port to the other (not the uplink) and it seemed to be working ok except for the PC that's hardlined into the DSL box. The other two wireless comps were working fine. Any advice would be greatly appreciated... I really just want to boost the signal a little bit so I have a steady connection. Thanks in advance,

    My PC is on the other side of the house as the router, the laptop in the middle room, and the router and other PC is in a room with the router. The channel on both routers is 11 because I've encountered problems with phones before. Its definitely a signal issue because I always connect with low signal strength and frequent drops. The Linksys has a stronger antenna than the DSL box does which is why I'm wanting to use it as an AP, even if I have to hardline it into the DSL box. Thanks for the reply.

  • Linksys wrt54g setup issue

    hello all,
    ive recently setup a cisco modem with a linksys wrt54g i had lying around for a friend.   i enabled the security (WPA/WPA2) and changed the name for the wireless connection. I restart every thing and i see the new name wireless secured connection but unfortunately a while later i see that the original unprotected 'linksys' access point still available. ive tried resetting the router and doing the process over a couple times. first by enabling the password and then changing the name and vice versa but i always see the unprotected access point show up again and again and its driving me crazy. i know its my router as well because when i disable the router both connections are lost. so basically my router is showing 2 names.
    any help would be greatly appreciated.
    thanks!

    Did you try removing the entire preferred network from the preferred list? If not then try to remove the entire preferred network from the list and then check it still shows the default network of the router “Linksys” or not. Here is the link for removing the preferred wireless network from the list:

  • Airport Express as wireless client for Linksys WRT54G (v2)

    Hi gang. I've been trying without success for some time to get my new AX configured as a wireless client on my existing network. Here's the particulars:
    Linksys WRT54G (version 2, latest firmware), 802.11 b/g, channel 6. MAC filtering is enabled, and the AX's MAC address has been added to the persmissions table. WPA shared key security is enabled. AX is latest firmware, 6.3.
    I can access the AX no problem by connecting it via ethernet/cat-5 cable to my router. I see it in the list of connected devices on the Linksys admin page, its IP address, etc. I can configure it, no problem. Except that every time I configure it, it reboots and never joins the wireless network, no matter what I seem to do.
    Here's my normal procedure:
    - Access AirPort Admin Utility
    - Select the AX from the first screen, then click Configure. Up comes the configuration screen.
    - Click on Airport tab.
    - I change Wireless Mode to "Join an Existing Wireless Network (Wireless Client)" and enter my network SSID in the Network Name box.
    - I then click the Wireless Security button, then select "WPA2 Personal", then click "Set Pre-Shared Key" and enter my WPA key, exactly as it appears in the Linksys wireless security page. I save the configuration and the AX reboots.
    After that, I wait for half a minute, then the flashing amber (problem/no connectivity) light returns.
    I'm completely frustrated with this thing. I've searched some other postings in these forums and on the net and tried some of it but it doesn't work for me. My wireless or network setup is pretty standard stuff, so I don't get why this thing won't join the network. I don't have these problems with any other devices.
    Any help is greatly appreciated!!

    I am experiencing the exact same problem here... I can set up a new network to this device, but cannot set it up as a client on my existing linksys network. I believe I have followed the procedure precisely yet no dice. The iTunes plays on the new network albeit on a weak signal which cuts out periodically. My thought was to put it on the linksys router with a stronger wireless signal...

  • Macbook Pro/linksys wrt54g slow wireless/wired network connection solution.

    I was pulling my hair out looking for a solution for this and it did not seem anyone had too much luck here. Hopefully this will help you all...
    Setup:
    - Macbook Pro, Mac mini, 2 windows boxes (not mine), 1 linux box
    - Linksys WRT54G v6 with dd-wrt installed. This solution should work with the standard WRT54G firmware.
    Symtoms:
    - All other computers performed fast on internet speed tests and on network transfers.
    - Macbook Pro Internet connection was slow (40KB/s on both the wired and wireless network using wpa)
    - Macbook Pro internal connection was slow (2MB/s on both the wired and wireless network using wpa)
    Things I tried to resolve this:
    - Disable IP v6 (no effect)
    - Set DNS Servers field to the dns servers as reported by the router. (Increased the initial speed but this quickly decreased making it useless... not to mention impractical)
    Thing that resolved my issue.
    - Disabled STP (Spanning Tree Protocol) on the router. In the DD-WRT it is towards the top of the Setup tab. I'm not sure where it is on the default firmware sorry.
    Hope this helps someone

    Darin,
    You're right - there are a lot of issues about MBP WiFi. I think there's a major problem with it.
    If there was a ..."major problem with it" you would see more complaints than wifi just being among the top 10 discussion items in a trouble shooting forum. There are millions of MBP users many of whom, like myself, use wifi every day without issue.
    Your statement "They exchanged it for a new machine. Worked fine in the store - but when I got it home, I was still getting very slow speeds." would lead one to suspect maybe interference from some source or a configuration issue rather than a "major problem".
    You probably already tried changing the channel, resetting your router, changing the security scheme, elimination possible sources of interference, separating your components (router, computer, external monitor, ...), etc. but maybe starting over with a default configuration will help isolate the problem.

  • Linksys wrt54g setup????

    hey,
    i am having trouble getting my Linksys wrt54g v8 router set up with cable internet. since i can't use their setup disc, i am having to do it manually, but i am not sure what i am doing. i have tried to follow the instructions online, but i still can not get the Internet indicator to light up on the router. i really don't think this is an Airport problem (at least not yet), but i just can't connect the modem to the router.
    i know how to access the router using an ethernet cable, but once i get to the Linksys setup in Safari i get lost. i tried changing the IP address in the router setup and it says, Settings Saved, but then it kind of locks up. i press Close, but it won't let me go anywhere from there.
    can somebody help me with this? i need detailed idiot proof instructions!
    thanks!!!

  • Re: Topic: Linksys WRT54G and WDS

    Hi all - this topic was in the 'User Tips' section of the forum, and I'd really like to ask the author 'Frank Canzolino' a couple of questions about certain settings for the Linksys before I proceed with trying to get the APX to work with it...
    For example, it says in step 4 to copy the MAC address seen in the 'status' tab - is that the MAC address of the Linksys router or the MAC address of the computer I'm working on?
    And I also have extra security measures set up that I'm concerned about - I have MAC filtering turned on, for example, as well as a trusted IP range which I'm not sure the address of '.201' would fit into. My range is basically completely occupied with 5 different machines and a Nintendo Wii - not sure where the APX would fit into the whole equation...
    Any help would be appreciated - does this board have a PM or 'email user' feature? I was trying to get a hold of the original poster, but the most I can seem to do is 'subscribe' to his posts...

    The Linksys WRT54G.
    ...I have MAC filtering turned on...
    Turn it off. MAC address filtering is not a real security feature. The MAC addresses of wirelessly connected clients are easily captured and cloned.
    Any help would be appreciated - does this board have a PM or 'email user' feature?
    Not sure what a "PM" is... The only way to directly contact another poster is if they have their e-mail address listed in their user information. Click on their name and you will see information on that user. It appears that Frank does not have an e-mail address listed.
    If you have detailed questions, post them here and someone will probably have an answer.
