WRT54G v8 Security Slowdown

Hi guys, I just replaced my WRT54G v6 by a WRT54G v8 because the last one kept dropping connections all the time. WRT54G v8 works fine with my wired computers and my laptop until I put WPA or WEP up, then I can't connect from my laptop anymore or I get a very, very slow connection at best. I've upgraded the firmware and no luck. Can anyone help? Thanks.

Problem fixed by using a AES over TKIP key. Don't ask me why. lol

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.

WRT54GS WEP Security Issues

I have used a WRT54GS for a few years with MAC filtering but no other security. A few months ago, I decided to add WEP security. While using WEP security, my wireless connection would go from an excellent signal to dropping randomly. Additionally, internet browsing would be very slow at times to the point of being unusable. When I disabled WEP, these issues went away. What should I look at to troubleshoot this issue?
Thanks.

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…

WRT54GS Wireless security two routers (WDS)

2 WRT54GS
Wireless connection between routers.
No1 SSID test (connected to ADSL modem) disabled security
No2 SSID test1 disabled security
After some hard work I was able to make a wireless connection (50m/150ft) between two WRT54GS routers. But when I enabled security (WPA-TKIP) on the router (test1) that is't connected to the ADSL modem, it could't connect to intenet anymore, only to the secured router (test1).
I would be very happy for some tips how to enable wireless security on both routers.

Under the tab WDS I just added the wireless mac from the other router.
test added test1's wireless mac address as LAN
test1 added test's wireless mac address as LAN

My friend has the same router and we haven't noticed a WDS tab in the setup page of this router. Can you mention the exact firmware version installed on your router?

Limited Connectivity with WRE54G to a WRT54G with security disabled.

Hello, I have a WRT54G Router and the signal barely reached my room, so I got the WRE54G, however when I plug in and auto configure the WRE54G I get Limited Connectivity. I am computer savvy and know that my router's wireless security is disabled. I'm using an HP running Vista. I've already held in the reset button and powered down the WRE and then auto configured but the problem persists.

(xp pro) same problem but i noticed as signal strength increases, the connectivity went away. unplug expander and connectivity comes back and of couse signal goes low.

WRT54G Wireless security setup

I'm having some trouble setting up wireless for this router. I set up WEP and entered a passphrase. When i try to connet to the network it asks for the passphrase. When i enter the phrase it says the network security key is not valid. Any ideas on how to fix this. Tx in advance

With WEP, you must enter WEP "key 1" (found in the router) into your computer, not the WEP password or passphrase.

WRT54GS, How secure is my router/laptop setup?

Hi, thanks for reading this. I am new to routers and networks. This is my router setup: Wireless/Basic Wireless Settings Tab: Wireless Network Mode = Mixed; Wireless SSID Broadcast: Enable; Wireless /Wireless Security Tab: Security Mode = WEP; Encryption: 128 bits 26 hex digits.
My laptop setup: Wireless Network Connection Properties/Wireless Networks Tab, under Preferred Networks, my network’s Properties contain: Connect even if this network is not broadcasting: (Checked); Network Authentication: Open; Data encryption: WEP. Is this secure enough? Should I change anything? Thanks.

My Wrt54gs blocks secured sites and games.

I have posted here before and got no help, it blocks any site that has https and even blocks me from connecting to: Warcraft 3, hamachi, and anything with an http popup. It is connected to with ethernet wires, and i have done power cycles countless times. It worked perfectly before I got this router. Any help would be appreciated.

I think Your needs
Follow these steps to upgrade the firmware on the device: -
Open an Internet Explorer browser page.In the address bar type - 192.168.1.1
Leave the username blank & in password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on
"Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the
same page OR it will say "Page cannot be displayed".
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and
re-connect the power cable...Now re-configure your router.....
Do all that things after that i think it will work Fine.

Airport Express and WRT54G v8

Airport express firmware: v6.3
WRT54G: v8
I'm unable to get my Airport Express to join my existing wireless network in Client mode. I've been able to get it to join other wireless networks using WPA, but with my new WRT54G v8 I haven't succeeded;
- Has anyone got an Airport Express to join a WRT54G v8 wireless network?
- Does the Airport Express support WPA2 when joining a non-Apple 802.11g network? It just shows WPA on the drop-down box for me.
- Is the channel selection important?
- For WPA, I've previously had to enter a $ before my ASCII-format password. Is that true in general for WPA and WPA2?
Having owned this Airport Express for 4 yrs, I have to say I'm dismayed by the level of frustration I've had with it, but I'm locked into it because I used Itunes.

I have the exact same problem. I purchased the airport express yesterday, and trying to hook it up in client mode, wirelessly to the wrt54g to be a print server. I set it up with the ethernet patch cord attached to the airport express and the wrt54g. It gets set up great and I can print and attach my clients (2 windows and 1 mac) wirelessly to the wrt54g network. If I leave the ethernet connected within 5 minutes my wireless network slows to a crawl and then stops traffic. If I disconnect the ethernet cable instantly the network returns to normal speed. But the airport express is no longer reachable. Granted it doesn't have the same IP and has to re-establish connection. However, it never re-establishes and flashes amber. Seems like it has to be security related as it seems to connect OK when the ethernet cord is attached.
I assume that to set the airport express up in client mode that the first configuration has to be made with the ethernet cord attached. Then when it resets itself to re-read the new configuration that I am supposed to unhook the ethernet cord. As it should be talking to the wrt54g through the wireless connection rather then the hard ethernet connection.
The setup steps I go through are:
- push the hard reset to get to factory settings
- connect ethernet patch cord from airport express to wrt54g
- bring up airport utility on macbook pro
- airport is found and press continue
- create a password - continue
- select I have a network - continue
- select join the network wirelessly - continue
- select my network from wrt54g
- select security
--I have tried the 40bit with the wrt54g 64bit WEP
--I have tried 128bit WEP on both
---neither works...if I try something else I need details on how to set it up
- continue and wait for when it restarts....
- If I leave the ethernet cord in, and switch back to the wrt54g wireless network, the airport express shows up in the airport utility very quickly. and seems to work for a while before taking my wireless network down.
- If I remove the ethernet cord and switch the macbook over to the wrt54g wireless network, the airport express never shows up in the airport utility and the airport express flashes amber. From the manual, this says there is connectivity issues. And through process of elimination, looks like the airport express can't get passed the security with the wrt54g.
So, I too, look for assistance.
PS. I have had the wrt54g for a couple of years and have not upgraded firmware so if that is necessary then I can do that.
PSS. At the very first airport express setup there was a new firmware loaded. Does this have to be re-applied if the airport express is hard reset (ie, paper clip in the reset hole for 10 seconds)?

WRT54G - cannot acquire network address

Hi All,
I having a particularly difficult problem I have not been able to solve. I've searched linksys forums, compaq forums, and google in general. Here are the particulars:
EQUIPMENT:
Linksys WRT54G Ver 3 router
Compaq Presario V2000 laptop
with Broadcom 802.11b/g WLAN (built-in)
PROBLEM:
When attempting to connect wireless to the 54G v3, an IP is never successfully acquired from the DHCP. It fails during the "acquiring network address" phase, and returns with "limited or no connectivity". IP acquisition failure is confirmed with an IPconfig address of 169.254.x.x (APIPA).
CONFIGURATION:
1. this is a new installation (laptop & router are clean, out-of-box)
2. Vanilla parameters on WRT54G (no security, etc.)
3. Upgrade firmware (on 54G), run factory reset to default parameters, assigned a SSID = sully
THINGS TRIED:
1. Compaq works FINE when connected wireless to another router (54G ver 2).
2. A different laptop (Dell) works fine with the Ver 3 router (wireless).
3. Wired connection works fine with Compaq to Ver 3 router.
4. Upgraded firmware on 54G ver 3 to current.
5. Download & re-install broadcom drivers from Compaq (which are actually OLDER than the ones originally on the machine)
6. Tried adjusting beacon, fragmentation & RTS as per a posting elswhere on this site.
7. Tried MS patch KB884020, as per a posting elsewhere on this site (and have since backed it out).
8. Tried resetting the TCP/IP stack as per MS KB299357 & KB811259.
I'm stumped and apparently so are all the standard tech support channels.
Any Ideas?
PLEASE (I don't mean to be arrogant - just frustrated with inadequate/incompetent support) - don't send me the "canned" newbie "try this" responses. EVERYTHING has been tried and this simply makes no sense. I appears to me to be a problem specific to compaq/broadcom & linksys 54G ver3 and no one wants to take ownership of the problem.

I have exactly the same problem with same laptop Compaq Presario V2000 with the same network adapter, although I'm using a different router BEFW11S4. I was able to get connection by using an static IP and DNS address, however I can't go online. Tech support hasn't been able to help me so I wanted to know if you were able to get a solution to your problem.
By the way, I can use my laptop with a Netgear router and I don't get this problem.
Thanks

Can't open a website after installing the router.

I just installed the wireless router, WRT54G, and secured wireless on it. Did not do anything else. I finished and came back to my wired connection and my usual business of the day and I noticed I cannot open ONE image hosting website. I could before and once the setup was done, I get the "server cannot be found". I can though open the site on the wireless connection and browse it. But not on wired. the website is www.photobucket.com and I really need access to it on my wired connection. Since the problem appeared after the install and turning off firewall and changing browsers does not solve the situation, I suspect it has to be some setting in router settings. Anyone can tell me how to remedy this situation? Thank you

Pls read my post on "Internet Connectivity", seems, at least for the time being to have solved my issues. fish

Error 0x00000709 Networked printer not working in a home network with HomeGroup enabled.

I should start by describing my network by device.
Gateway device - Motorola SB5120 SURFboard cable modem
Router/WAP device - Linksys Wireless G Broadband Router with 4 port Switch Model: WRT54G v4 Security: WPA2 with firewall.
Windows 7 Ultimate Desktop with Homegroup enabled (Printer driver installed & ethernet wired)
Windows 7 Pro Laptop set to homegroup for the Desktop (Ethernet wired and Wireless depending on the situation)
Windows 7 Home set to homegroup for the Desktop (Wireless)
Brother Printer Model: HL-2170W (Wireless)
HP Printer Model: HP Officejet 6500A Plus (Wireless)
What have I done?
Installed drivers on 2 of the 3 computers. The final computer (Win7 Home) was added in later and works fine when connecting to the internet through the WAP. However it does not even find the printer when trying to install the driver which is a part of the
process for driver installation for the Brother Printer.
I had set up the printer for two of the three computers and had it working at one time however in trying to get the printer set up for the final computer I somehow have messed up those settings.
During that setup I tried to move the printer to a networked printer (It was shared before and installed on the network with both the Desktop and the Win7Pro lappy able to print but it would not print for the new arrival to the Homenetwork. This caused
me to seek a solution which involved installing the proper driver in the Win7Home and the discovery that the driver installer could not find the Brother printer at all which prompted the moving of the printer to a networked printer.) (The Win7Home computer does
not find the HP printer either but that is a can of worms yet unopened.)
I am sure there are a few things that I did not do correctly and I may have left out some additional information which you may require. If I can help clarify this question please feel free to query me. I thank you in advance for your time and consideration.

Hi,
May I know that are these two network printer with network adapter? If they are installed on the network, you could add them and install the drivers for Windows 7.

How to set up a password or security using wireless g broadband router wrt54g

Hello Everyone I have had my router for a while and a friend mentioned I should password protect my connection so other people can't lech off of my wireless connection. My roter is installed and connected to my main office computer and I only bought it so i could use my laptop around the house. Everytime I go to profile then secuirty settings and try to imput any password and hit ok. Well after I connect to my wireless profile it comes up with my router has no secuirty turned on at this point. Yet I read from many sites that my router which is model wrt54g has secuirty features. Could someone please help me figure out how to password protect my wireless connection. THank you

Hit there exiledone1!
If there'd be any computer which is working through the router, you could get into the router's User Interface without any problems then. You need to get to this page so that you'd be able to do necessary changes on it's wireless settings.
http://192.168.1.1 would be the address, type this on the Address Bar of your Internet Explorer browser or Mozilla Firefox browser. If you'll be prompted for a login page, simply leave the username blank (or don't write anything on it) and your password would be admin. You'll be able to see the Wireless Tab once you'll be inside the page and below the Wireless Tab would be subtabs and one of them is Wireless Security. Just click on Wireless Security and you can choose WPA for your Security Mode. Just type in anything right on the WPA Pre-shared key field and this will then serve as your wireless password (a.k.a network key). Just make sure the length of the key would not be less than the count of 8 characters.

Network security - using two wireless WRT54G Routers

I have lots of ports on my router open for numerous family software applications that are all on one computer and I would like to isolate these risky activities from the rest of my network.
I recently read I could use two routers, plug one router into another, assign each a different starting IP address (such as 192.168.1.1 and 192.168.2.1). Then attach my at-risk PCs--to the router that's directly connected to my broadband modem, and all other computers to the second router.
Internet traffic to and from the unsafe PC area would then not reach my secure subnetwork at all.
I currently use a WRT54G V5...does buying a second one and using it as described make sense? It sounds like a rather inexpensive way to add security to my network.
I assume the second router gets connected from it's internet jack to one of the port jacks on the first router? Is there anything else that would need to be changed or set in either router to make this work?
Can I please ask if u respond to try and keep your response at a level that a non expert could understand.....I would really appreciate it!
Thanks for everyones advice!

Thanks for the quick response....it is disappointing to see that I would lose the ability to share files......I assume this is also true for printers as well??? Do you have another solution that you think would do a better job?
Anyway I did get a rather detailed response on how to make it work and it's in a fashion that even I could understand.
I thought I would share it in case anyone else had a interest to isolate a computer.
Thanks
With regards to your concern, the setup that you suggested does address your concern. With this setup, we are somehow creating two networks on your location. In this manner, the computer that needs the set of ports will not be part of the network of the second router thus, it will not be able to affect the other computers.
With this type of setup, we will just have to leave the current settings of the WRT54G v5 (as long as its working properly this time). All we have to configure is the second router wherein we will have to change its LAN IP Address and also, configure its wireless settings in order for the said router to provide wired and wireless connection to all computers connecting to it. Please allow me to give you the steps.
Once we have the second router available, please connect one of the computers straight to the second router using one of the four ports (Ethernet port). With the configuration, only the second router and the computer will be connected with each other.
Before setting up the second router, I suggest that we do a hard reset on the router to make sure that it is on default settings and that we have a stable connection during the setup.
Here’s how to do a reset:
1. Locate the reset button of the router at the back panel.
2. Hold the reset button for 30 seconds using a pen or a paper clip.
3. Release the reset button.
Configuring the Second Router:
1. Go to your desktop and double click on Internet Explorer (Located on the Start Menu in Windows XP).
2. When "Internet Explorer" opens type 192.168.1.1 into the "Address" bar and click on Go.
3. The "Enter Network Password" window will appear.
4. Skip user name and type admin (admin is the default password) as the password, and click OK.
5. Go to Wireless Tab.
6. Change SSID (e.g. Vic or your name or last name).
7. Change channel to 11.
8. Hit save Settings.
9. Click on the sub tab Wireless Security.
10. Set the Security Mode to WEP.
Using pass phrase Encryption Level 40/64bit (10 hex digits):
1. Type a pass phrase.
2. Click Generate.
3. Copy key1 on a piece of paper (10hex character).
4. Hit Save Settings.
For using manual key entry Encryption Level 40/64bit (10 hex digits)
1. Under Key 1 type a 10 digit character from A-F and 0-9 (e.g.: A0B3F58C9E, 0123456789, ABCDEFABCD).
2. Hit Save Settings.
3. Click on the Setup Tab.
4. Change the Local IP Address to "192.168.2.1".
5. Click “Save Settings”.
Finishing the Connection:
1. Shut down all computers.
2. Unplug the power from the back of both routers.
3. Unplug the power from the modem.
4. Wait for 30 second.
5. Connect the WRT54G v5 router (using its Internet Port) to the Cable Modem.
6. Connect the WRT54G v5 (using one of the four Ethernet ports) to the second router (using its Internet/WAN port).
7. Power up the modem.
8. Wait for the lights to stop blinking.
9. Power up the routers.
10. Start up your computer.
