WRT54g router DHCP problems (I think)

I just got a wrt54g wireless router for my organization hooked it up and started having problems. I set the router to use DHCP and *tried* to set the “Maximum Number of DHCP Users:” to 15 and clicked “Save Settings” but when I went back to that screen it would be back at the default (5), I have since tried to change it many more times and no matter what number I pick (2-230) it still shows up as 5. Anyway. 1st I connected my XP notebook and was able to access the internet (specifying that my computer obtain the IP address automatically) Next I connected my colleague’s vista notebook and he could access the internet. (specifying that his computer obtain the IP address automatically) Next I connected another colleague’s xp desktop (specifying that my computer obtain the IP address automatically) *Next* I tried another colleague’s XP notebook computer and started having problems. I specified that it should obtain the IP address automatically but it would not and kept getting a 169.254.x.x address instead of one like 192.168.1.x (it also keeps showing a subnet mask different from the one I specified on the router). I went back to my notebook (which had been working fine) and discovered that now (without my making any changes to my notebook) I am having the same problem. I am now having the above problem (computers not receiving addresses automatically) with all but one or two computers (the vista notebook continues to work). Someone on usenet suggested I try putting in an IP address manually so I did and it worked but #1 I need more than 5 computers to be attached at one time (the router refuses to accept any number higher than 5 [though I can specify *less* than 5, it will for example remember 4 and 3]) #2 The router should be assigning IP addresses to all the computers, I shouldn’t have to be putting in the addresses manually.

Did you try to flash/reflash the routers firmware? Try that and reset the factory default settings and cycle the power. Then reconfigure the router and let us know if it continues to do that.

WRT54G (v5) DHCP problem (MAC, APPLE, MAC OS) -- How to fix it

Ok, so I just got some instructions from Linksys support and apparently definitely got rid of the DHCP problem. Here they are:
Please reset the router before and after the upgrade.
To reset the router (make sure that the modem is disconnected when doing 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 and unplug the power adapter of the router.
4. Leave the router off for 30 seconds then plug it back in.
Click the link below to download and save the firmware:

To do a firmware upgrade, you can follow the steps listed on this link:
http://linksys.custhelp.com/cgi-bin/linksys.cfg/php/enduser/stdadp.php?pfaqid=557
Reset the router again after the firmware upgrade. You can then reconfigure it for Internet and wireless connection.

Hi, Malcolm:
Thanks for the post.
No, my new Mac Pro system does not have USB port on the Keyboard, cause I've opted for Apple's wireless blue tooth mouse and keyboard.
I do have 2 USB ports on the Apple's 23" LCD display, and Two USB ports on front side and two available USB ports on the back of the Mac itself.
During the Thanksgiving long weekend, I think I might accidentally singled out the cause of my problem.
I have my HP printer and one multi-card reader constantly pluged into the two USB ports at the back of my Mac, and always tried to use the front side USB ports for the 1GB USB Pen Drives, and that's where the problem lays!
When I unplug the Multi Card Reader from the back USB port, and suddenly all USB ports on my Mac works just fine with the Pen Drives!!!
So, for now, I plug the Multi Card Reader in one the the front USB port, and the rest of the USB ports on the Mac work with Pen Drives flawlessly, it seems that I sloved my problem for the time being...
As for those two USB ports on the back of my 23" Apple Display, They can not take my USB Pen Drives, as you've mentioned that it does not have enough power for the USB Pen Drives.

WRT54G V6 DHCP Problem

I have a WRT54G V6
I am use WPA 2 with AES
and useing MAC Filering
i have 1.02.2 7/02/2007 Firmware for the WRT54G V6
- i think it may be the Firmware

The firmware is the most current one on the site. There are no other options than that. Anyway what kind of DHCP problem are you having? Is your laptop getting "limited or no connectivity" when you try to connect wirelessly to the network?
Don't use AES. Most cards are only compatible with TKIP.
What kind of Wireless MAC Filter are you using "Prevent" or "Permit Only"

WRT54G Router DHCP leases

I would like to see the router DHCP leases on a screen in the firmware so you can see how many are being used and which ones. Who do I need to contact to pass along this suggestion?

I have the WRT54G V6.0 Router with firmware 1.01. I get the idiot of the week award for reading the manual and finding it on a page when logged in to the router. I just didn't look far enough in the software to find it before I posted. Sorry! All idiot bashing posts welcome..starting with the big DUH...........

WRT54G ROUTER CONNECTION PROBLEM

I have a WRT54g router.
Everything works great for a period of time even after turning the computer, internet modem and router on and off several times.
Then I turn everything on and the computer does not connect to the internet.
It go and connect the computer directly to the internet modem and I have internet access.
To be able to use the router again I have to reset the modem and input all the settings which I do with the setup disk.
I have been using channel six in case this makes any difference.
Any help will be appreciated.

connection DMS: HSD1.fl.comcast.net
IP address          :192.168.1.100
subnet mask      :255.255.255.0
IP address          :fe80::213:20ff:fec3:6913%4
default gatway    :197.168.1.1
ping                      : sent 4 received 4 lost
reply                      :bytes 32   time 1ms   TTL 64
It does not connect to the internet now but if I reset in the back of the modem and reload the setting via the original CD that came with the unit it starts to connect. Eventually one of the times that I power up it stops connecting to the internet although it still ping's out.
I also tried to load the update of the newer solfware but it does the same with or without the update.
Thanks for your help.

WRT54G - router/DHCP dies a few times a day

I have the same problem - WRT54G - all the machines at our place are macs with various flavors of OS X - mostly 10.4. Every few days - sometimes 4 times a day, the router stops working - basically the DHCP server stops giving out valid IP addresses and nobody - wired or wireless - can connect the the internet. It still appears to be connected the the net via the cable modem, its just the router part that is failing. This is very disappointing. Unplugging the WRT54G fixes it - but sometimes the same problem will happen 15 minutes later.

Wrt54gs router pppoe problem

hey guys,
I have a problem with my 'wrt54gs with speedboaster router'. My internet connection is with PPPoE. I've used the router option to connect it with PPPoE. The router gets connected with my ISP with PPPoE, gets the IP-s, DNS-es and everything, I can also ping any host with the router's diagnostic tools, which means that the router is connected sucessfully with PPPoE and is having internet, but the problem is that when the internet is shared through the internal network (the 192.168.1.xxx one), my computer gets IP with DHCP and also the ISP's DNS-es, but I the internet does not work. Something is failing while the internet is being shared from PPPoE to my computer. And one thing to tell is that the PPPoE network has the subnet mask 255.255.255.255 and the internal network has the subnet mask 255.255.255.0.
Anyone knows what is the problem??
best regards.

Ok, so it's cable broadband. You might want to enable MAC address cloning. Go to http://kb.linksys.com and search for anything related to "cable" internet. You may even try searching for your ISP name (eg: comcast).
Also, software that comes from your ISP (if any) is designed to work without a router "in between" modem and PC. If you have that installed, remove it.

WRT54GS Router torrent problem on 2 PCs

Hiya. I recently connected 2 PCs to a WRT54GS ver6 Linksys router. The PCs each use a WUSB54GS ver2.1 adapter to connect to it. Everything is fine, however I'm having a problem with torrents being limited on one PC. The first PC connects fine, everything runs smoothly and fast. However when I try to connect to the same torrent with the other PC, its greatly limited. Its never given full access, and whereas normally it would have 20+ seeders, I'm lucky to get 2. Download speed on the first PC is 100kbps, whereas the second is 5-20kbps. I've looked around the internet and been unable to find this specific problem. It seems as if 1 PC has been giving the OK by the router, but the other is being throttled back for some reason. Does anyone know how I can fix this? Thanks

Running peer-to-peer software is a known cause for router slow downs and disconnections. When a "torrent" is running, it will typically make over 100, and often over 200 connections. The router must keep track of all these connections. The router has a limited amount of memory to work with, so this leads to router slow downs and disconnections.
If possible, have only one computer running torrents at a time. Additionally, you can go into the peer-to-peer software and reduce the number of connections that the software can make. This effectively limits the impact that the torrent is having on the router, and this sometimes helps.
Alternatively, if one of your computers has this "slow" problem even when torrents is not running on the other computer, then perhaps you simply have a poor wireless connection. This can happen even with a 100% signal strength. There are many things that cause poor wireless connections:
First of all, give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
Poor wireless connections are often caused by radio interference from other 2.4 GHz devices. This includes wireless phones, wireless baby monitors, Bluetooth (including Bluetooth game controllers), microwave ovens, wireless mice and keyboards, wireless speakers, and your neighbor's wireless network. Even some 5+ GHz phones also use the 2.4 Ghz band. Unplug these devices, and see if that corrects your problem.
In your router, try a different channel. There are 11 channels in the 2.4 GHz band. Usually channel 1, 6, or 11 works best. Check out your neighbors, and see what channel they are using. Because the channels overlap one another, try to stay at least +5 or -5 channels from your strongest neighbors. For example, if you have a strong neighbor on channel 9, try any channel 1 through 4.
Also, try to locate the router about 4 to 6 feet above the floor, in an open area. Do not locate it behind your monitor or near other computer equipment or speakers. The antenna should be vertical.
Hope this helps.

MSI RG54SE router DHCP problem

Hi
I have bought a router RG54SE and tried to use port forwarding. It was all ok until I have turned off and on my PC for a few times. Then, my IP adress acquired by DHCP changed. But the local address used in port forwarding have not changed, so the port was then forwarded to another PC. The problem is IPs do not change time to time, but really often. I have more WIFI clients and DHCP always offers different IPs. Is there a way to force dhcp to lease IPs for a longer time or something else on this router without telnet?

Isn't know this router the static IP?? Can't to add IPs for MAC addresses? Why? this option be found some poorly, cheaper router.
Or if it is foundly in the router, please tell me where.
The firmware manufacturers make a firmware please with this option!
If somebody know the answer, please write it for me at a mail: [email addy removed]
Thanks!

Also having DHCP problems -- I think.

I've been able to get the NetBoot and NetInstall service working on my test network (a MacMini running OS X Server 10.5.? and completely isolated from my school network). On my test network, the server is providing the DHCP service, and everything works. When I try to duplicate this on the school network, my client machines will not see the NetBoot images. The only difference I can see is that my XServe isn't providing the DHCP service. That's happening somewhere else on the network. Let me back up here: We have a Novell/PC network. We also have one iMac lab which is served by an XServe. The XServe mainly acts as a file server, but also serves as an Open Directory Master for the iMac accounts. DNS and DHCP happens somewhere over on the dark side of the network that I have no knowledge of. When I initially set up the XServe, I set the network options to configure manually with a static IP that the network admin gave me. I surmised that maybe the NetBoot wasn't working because the Xserve wasn't getting DHCP. I changed it to configure via DHCP with the same static IP address. Still no go.
Thoughts? Questions? Jeers?

There can be only one DHCP server that distributes IP address for your network/subnets (It is 'technically' possible to assign multiple bootpd servers to different subnets.). There can also be only one Netboot server per subnet (It is, again, 'technically' possible to have one that serves all subnets that may be served by a single router, although you may have trouble convincing the person(s) in charge of your router configs to make that happen.). You need to turn off the DHCP service on your XServe.
If your network administrator has your campus divided into different subnets, then you need to manually set the IP address of your XServe to live on the subnet that you will have the server attached to. Clients that you wish to Netboot must also be on the same subnet as the server. You can try using Mike Bombich's NetbootAcrossSubnets if you wish to try to get it to work on more than one subnet on your campus.

WRT54GS dhcp problem

Hello, At our office we use a WRT54GS router (firmware v7.50.5) . The configuration is pretty simple : uplink switch -> Linksys router -> wireless & wired network . The local network setup chosen is with dhcp enabled.The problem is that the dhcp acts like a "dhcp-relay",it forwards the dhcp requests .And on the same vlan our wan is,we do have a dhcp server ; our computers get IP from there. In the setup page I have no option regarding "dhcp relay",it just doesn't work.Why it is forwarding the requests and not processing itself ? Thank you,

problem solved,there was a loop in the LAN.

Problem connecting to same game server, WRT54G router.

Hello I have a WRT54G router, me and my brother cannot play on the same game server on Team Fortress 2. It kicks the person already in the server when the other person joins and gives a connection issue. We think the game server cannot take the same IP twice in the same server.
We checked IPs on ipchicken.com and we're sure the router giving us the same IP is the problem. If it matters we're connected with ethernet cords, not wirelessly. Is there any way to change the IP addresses or fix this?
Thanks, Matt

The game server will only see the single IP address assigned to the modem or router by your ISP, and won't see the individual computer's locally assigned addresses.
So, unfortunately I see no way around this without subscribing to a separate internet connection with your ISP.

Online Games Problems With WRT54G Router

Hi There ppl,
I have a Lan House with 50 comps working, and most of my costumers are looking for online games entertainment (Cabal Online, Ragnarok, Dota, CS, 9 Dragon etc). We have an 8 Gb DSL connection and another one of the same speed for back-up (not running simultaneously at the moment). We should be having outstanding results for online gamming (and we were before installing the new router) but we are having several problems since we install a new LinkSys WRT54G router here. Our physical configuration is the modem, followed by the router, than three DLink Switches(24 ports) and my main computer. Everything cable
What we noticed is that the Internet connection looks normal (even using the command "ping", nothing strange appears, no timed out at all!) but online games (specially the above mentioned) have an intermitent connection. (Some times they connect, some dont)... Looks like it happens usually when I have the house crowded, but already showed also with it empty.
Another issue is that I am using the LinkSys Advisor to help identifying this problem, but I am getting even more confused, because its giving new information each time I refresh the "my network" window. Also happens when showing "My Network Settings" on the Support Tab.
Im using Firmware 8.00.0, what I think is the newest.
I didnt try any forwarding port issue yet, as I would like to receive more information about it (never needed to configure anything related before). Concerning the MTU value I already tryed withou any significantly result.
Please If anyone had the same problem, or have any idea of other possible tests, i would appreciate a lot.
Thank you and have a great day all

Hi there Helm,
Tks for your attention and reply to my issue!! Yesterday right after posting here (when we closed the doors and I could be able to work on it) I did get the latest one (8.00.2) and also set up manually the MTU value to 1500 (standard is automatic). I also unckeck the "anonymous internet request bock", "Multcast filter" and "Filter NAT forwarding", all of them were checked as standard. I also checked the "HTTPS Internet Access" (standard is only HTTP).
At a first moment I could get a very low sensitive better result (but the Lan was closed, so I had the entire 8Gb for my requests). I came back to work right now, and we have about 30 ppl in, mostly using the Internet, MSN and so... I am trying yo connect to Cabal Online, and GG-Esports (Warcraft, Dota) both of them giving the same problems as always... I am really getting tired and disapointed with LinkSys, I really though I would have much more than I am having right now.
Anyway I gonna keep trying each night to see what I cant get. I do post here If I find any solution (or if I really decided to move to another brand)
Thank you a lot and have a great night out there

Need help with understanding static vs dhcp on wrt54g router

I currently have a NAS200 device attached to my WRT54G router. The WRT54G is in DHCP mode so as to allow my various laptops and cameras to be accessed over the internet. What happens is that when I have a power failure the NAS200 is given a new ip address even though its plugged into a service port. I am then forced to go into the router and change the port mapping to whatever port the router has given to the NAS. Is there any way to keep the NAS200 at a specific ip address regardless of router resets. Thanks Hexmate

You have to set the static IP address on the NAS. The NAS is currently configured to use DHCP. Change it there to set a specific static IP address. The router itself does not have to option to set a fixed IP address to a specific device via DHCP.
For static IP addresses make sure to choose an IP address which is not used by any other device nor is inside the DHCP server address pool of the router. With default configuration a Linksys router uses 192.168.1.1 and the DHCP server uses 192.168.1.100-149, thus you have addresses 192.168.1.2-99 and 150-254 available.
Use an static IP address like 192.168.1.50, netmask 255.255.255.0, gateway 192.168.1.1 (if the NAS needs internet, e.g. for time synchronization) and DNS 192.168.1.1. That should do it. Again: this has to be done on the NAS device. The router has no option for that.

Wireless to Wired PC problems with WRT54GS router

I am helping a friend troubleshoot a home network with a high-speed DSL line, WRT54GS router, 3 wired XP PCs and two laptops connecting to the router via 80211.g
The desktop PCs see each other on the network and can share files and printers.
However the laptops via WIFI don't see the wired desktops on the network, nor can the desktop PCs see the laptops on the network. I tried running the XP network wizard on each laptop with no luck. I tried some ping tests with the following results:
When I ping a laptop from a desktop, I get a return ping
When I ping a desktop from a laptop, I can NO return ping.
When I ping the IP address of the router from a desktop, I get a return ping
When I ping the IP address of the router from a laptop, I can NO return ping.
I tried disabling the firewall features internal to the router with no luck.
All machines are running Macafee total security with a firewall. I made sure the firewall was disabled for these tests.
I would appreciate some advice.
Thanks

Turn on file & printer sharing on all computers. Make sure they are all on the same workgroup. Do not use network wizard.
Log on to the router and setup your wireless settings & wireless security. Change the network name from Linksys to something else. Copy these settings on a piece of paper. Now go to your laptops and find the network you just created. It will ask you for the key or passphrase. Input the passphrase you just created. If it does not work you will have to manually configure your wireless settings that you written on paper.
