WRT54G firmware Mac DHCP conflict

I updated my WRT54G version 6 to firmware version 1.01.0 and (after 2 days when things worked fine) lost the ability for any of my 3 Mac computers (intel iMac and pismo powerbook) to get an IP address either by wired connection or wireless connection to the router. My Windows laptop connected just fine by wired and wireless connections. The Macs could see the router if manually set to IP 192.168.1.50, but did not get an IP address if set to DHCP. No amount of resetting router, modem and computers helped. I reflashed 1.01.0 using the PC but that did not help. I flashed back to firmware 1.00.9 and immediately got back wired and wireless connections with all of the Macs. There are at least three other reports of people solving exactly the same problem posted in the Apple discussion boards with other Mac models.

Can I use my WRT54G as a DHCP server only? I've got 5 dynamic IP's from Time Warner..

Hi everyone, I'm wondering if I can use my WRT54G as a DHCP server only only my network, without having to have any of my PC's plugged into it's router ports? I looked at the settings but I couldn't get it to work.
Here's why: I just got Time Warner Business Class cable internet which comes with 5 dynamic IP's. I want each computer, well 4 of them at least and 1 for the WRT54G, to have a unique IP when accessing the internet, and the other computers (5 more computers) to use the DHCP server in the WRT54G to get a NAT IP for use on the internet.
We play Diablo II on the internet and only 4 computers can be connected through 1 IP, so that limits us in my current configuration.
Current Equipment: One WRT54G, one Netgear GS116 16 port gigabit non-managed switch. One Time Warner Cable modem. Also attached to the network is one HP network printer, a Buffalo LinkStation NAS and a Zensonic Network DVD player.
Current config: Cable modem --> WRT54G --> Netgear switch.
Ideal config: Cable modem --> Netgear switch --> WRT54G.
With my current config, I am not taking advantage of the 5 dynamic IP's, but all the computers connected to the Netgear switch or the WRT54G can connect to the internet and the NAS.
So my ideal config (where I don't have to buy anything and where all the computers can print and access the NAS) is to connect all the computers and devices to the Netgear Switch and somehow force 4 of the computers and the WRT54G to get a dynamic IP from the cable modem, while the other computers and devices use the DHCP server on the WRT54G to get to the internet.
Is this possible?
I called Time Warner Cable and they weren't any help. I called the Linksys sales department and they weren't of much help either.
I suppose that I could purchase a new 8 port switch and attach 4 computers, the cable modem and the WRT54G to it. Then attach the Netgear to the WRT54G to accomodate the printer, NAS, and the other 5 computers. But in that senario, the 4 computers connected to the new switch can't print and can't reach the NAS. And geez, some computers would have to go through 3 devices to reach the internet, which has got to slow them down.
I did read about the Linksys EFG120 which has a DHCP server, but at $400 and only 120 gigs, it doesn't work for me.
I called Time Warner and the cost of more dynamic IP's is prohibitive, I'm already paying $79 a month for this internet and they want another $50 a month for 7 more dynamic IP's and that wouldn't help my NAS or my printer.
The cost of a 16 port gigabit switch with DHCP is an amazing $800 or so, which is out of the question.
Sorry for being so long winded and thanks for reading this far. I'm looking forward to any replies.

That is a hell of a setup. I don't know if it would be easier and cheaper to either buy a real router like a Cisco, get fixed IP addresses and a RV042, or buy 4 network cards for the four of the five computers which need the internet access for gaming.
O.K. First your setup:
1. You wire the modem to the 6-port switch.
2. You connect the remaining 5 ports with the WAN ports of 5 WRTs with DHCP on the WAN interface.
3. You configure each WRT with unique LAN IP addresses in the same subnet, e.g. 192.168.1.1/255.255.255.0, 192.168.1.2, 192.168.1.3, 192.168.1.4, 192.168.1.5.
4. You turn off all DHCP servers except on one, e.g. 192.168.1.1. That router will be the default router and internet connection for any client which gets dynamic LAN addresses (as fallback or guests, I would not configure the NAS or printer with DHCP addresses if you have everything else on static IP addresses). You can certainly disable all DHCP servers if you want, too.
5. Now you connect all WRTs with each other.
5a. You connect port 1 of the 1st WRT with port 1 of the 2nd.
You connect port 2 of the 2nd with port 1 of the 3rd.
Port 2 of the 3rd with port 1 of the 4th.
Port 2 of the 4th with port 1 of the 5th.
(Do not create a loop connecting port 2 of the 5th with port 2 of the 1st!!)
5b. You buy another switch and connect each port 1 of each router with this switch. This has the advantage that you don't have a long cascade between the 1st and the 5th router like in 5a.
6. You connect all devices to the LAN.
6a. If you did 5a, you will probably put each computer to the router which internet connection it uses. The NAS and printer could go anywhere.
6b. If you did 5b, you hopefully bought a 16 or 24 port switch. Then you plug simply everything into that switch. Otherwise you can certainly use the free ports of the WRTs like in 6a.
7. You configure all your devices with static IP addresses. For instance,
IP 192.168.1.11
netmask 255.255.255.0
gateway 192.168.1.1
For the DNS servers I would highly recommend to use the DNS servers of your ISP directly and not use the relay on 192.168.1.1.
The gateway address defines through which router the computer connects to the internet.
8. You may still have to configure port forwardings on the router to the game computer if required for the game.
An interesting alternative to this setup might be to buy 4/5 network cards for the 4/5 computers with direct internet access. Then you use the one network card to connect to your single LAN behind your single WRT. The other network card goes into the switch behind the modem and has direct internet access. You then have to tell Windows which of the network cards has the default gateway for the internet connection (to prevent routing all traffic through the LAN and the WRT to the internet). One game computer would have to be behind the WRT.

Auto clear ip dhcp conflict *?

Is there a command or config that will make a router automatically clear ip dhcp conflict * on a regular basis? I have a site that constantly has a problem with DHCP due to conflicts which is fixed simply by clearing the conflict table. If we could automate this, it would be great.

I modified your example to solve similar issue. I wanted it run every hour though. Here's how to modify Cron format:
https://en.wikipedia.org/wiki/Cron#Predefined_scheduling_definitions
My EEM simple script:
DV-CORE(config)#event manager applet ClearDHCP
DV-CORE(config-applet)#event timer cron cron-entry "0 * * * *"
DV-CORE(config-applet)#action 1.0 cli command "enable"
DV-CORE(config-applet)#action 2.0 cli command "clear ip dhcp conflict *"
DV-CORE(config-applet)#action 3.0 cli command "clear ip dhcp binding *"

DHCP Conflict Detection & Win 7 Firewall..

       This may be a stupid question, but I can't quite find the answer....
   We have a small network, about 200 computers (Server 2012), Win 7 workstations (Very Few XP's left)
I had one workstation detect an IP conflict (XP if it makes any difference), and it just was assigned another address
and it was on its merry way.   I took a look at the DHCP server and realized that I never turned on DHCP Conflict detection.
I turned it on and set it for 1 attempt.
    So for the heck of it I pinged the workstation and DNS worked but ping is blocked on the workstations firewall.
    Which made me wonder if I should push out a GP to allow ping to all the workstations???? (Question 1)
     Question two: If I do that to all the workstations, what would stop it from happening if someone brings a "guest"
     laptop into the building??
           What would be best options? or is it working as it should and I am just Paranoid!! LOL
                           Thank You in advance for any advice
                                           Wolverine..

Hi,
According to
this article, Client computers running Windows Server 2008, Windows Vista, Windows Server 2003, Windows XP, Windows 2000, Windows NT 4.0, Windows Millennium Edition, and Windows 98 automatically check to determine if an IP address is already in use before
using it. I think this behavior still exists in windows server 2012.
On the server-side, when a DHCP client requests a lease, a DHCP server checks its pool of available addresses and assigns the client a lease on an available IPv4 address. By default, the server checks only the list of current leases to determine whether an
address is available. It doesn’t actually query the network to see whether an address is in use. If you enable address conflict detection, the DHCP server uses the ping process to test available scope IP addresses before including these addresses in DHCP lease
offers to clients.
In addition, each additional conflict detection attempt delays the DHCP server response by a second while waiting for the ping request to time out. This increases the load on the server, so it is not recommended to set the value greater than two for ping attempts.
Hope this helps!
Best regards,
Susie

WRT54G, Firmware Version: 8.00.2, Stops routing after a day, Requires Power Cycle to Work Properly

WRT54G, Firmware Version: 8.00.2, Stops routing after a day, requires a quick 10-15 second power cyc... work properly for a day or so before powering down again….
I was using for years the BEFW11S4 Model without any issues before it finally failed. Due to loyalty, I went out over a month ago to purchase the current model. The problems did not pop-up until month of December… The issue had me thinking at first was the internet connection…
Any advice on dealing with this issue… Is it a Software and/or Hardware? It appears to be a software related condition…
For those other WRT54G users that appear to be having similar issues, regardless of the firmware, it would appear we all seem to be facing the same condition of resolving the issue after a power cycle…
Is there anyone out there that has already resolved this issue (e.g. Configuration changes)? Does anyone have input that Linksys is actively working on this issue?
Although I am sure we will find a solution, having to cycle the power is a bit disappointing since my older model had no such flaws with my current internet connection…
Thanks for the support out there….

If you have an Intel wireless card you can try this. I came across this link on the forum a days ago and it seems to help. The problem is that my problem was much more intermittent than some people are experiencing. It mainly seemed to appear when undocked the computer or if there was a power outage during the day. I would be interested to see if it works for you or if I'm just chasing my tail. I've seen other suggestions for changing the thresholds in the router which may be related.

DHCP conflict due to Gratuitous ARP.

One of my wireless VLAN DHCP scope on cisco core switch is often exhausted due to Gratuitous ARP.
Please help me to check what is the cause of this.

I have a VLAN with DHCP SCOPE and layer 3 configured on core switch.
the DHCP pool often gets exhausted and when I do show ip dhcp conflict most of the IPs conflicted due to Gratuitous arp

WRT54G v7 WAN DHCP client problem

I've recently started having a strange problem with my WRT54G. Internet access is via a Cable modem and has been working fine for months, and the cable modem works fine so I suspect the problem is with the router. However the router is also working, mostly, so I figured I'd see if anyone here has any suggestions. Here are the details of the problem:
The router WAN configuration was set to DHCP.
It used to happily pick up a new IP address from the cable modem whenever necessary.
One night the router stopped picking up an IP on the WAN side. (nothing was changed. I'm the only one in the house who goes anywhere near the router)
Connecting the modem directly to a PC works fine (suggesting the modem's DHCP server is fine).
Copying the WAN IP config from the PC to the router, as a Static IP, also allows it to work when the modem is plugged back into the router and the router to a PC (which is how it's setup now, but it's a pain to have to mess with the physical connections and manually reconfigure the router every time the modem drops a connection (which is another issue, but not one for this forum...)).
So both the modem and the router seem to work except for the router's DHCP client. It works fine as a DHCP server for the LAN.
The firmware was already upgraded (and working), I've followed the standard power-cycle procedure, I've released and renewed the IP via the Status tab in the web interface, and I've tried resetting the router using both the button on the unit and via the web interface to revert to factory defaults.
Any suggestions?
Solved!
Go to Solution.

I also had this problem which occurred after >2 years of the router working fine. After changing MTU to 1300, cloning the PC MAC address, and power cycling the router and modem fixed the problem. But I was curious to see which change did the trick, so I changed both back to the default (MTU = auto and not cloning the MAC address) and it worked fine! I think the router problem is intermittant and may appear to be fixed by changing setting, but I fully expect it to reoccur.

WRT54G - Cannot get DHCP to resolve

Hello, I have a WRT54G v 5.0 that I had got 2 years ago. It has worked wonderfully in what it had to do, but now it's cutting out on me for no apparent reason. I have a relatively simple setup Optimum Online -> WRT54G -> 2 computers [wired] and a wireless access point [for a laptop] so traffic really isn't an issue. In the 'Status' section of my router's webpage, I try to DHCP release/renew to no avail, I get returned a 0.0.0.0 address. However, when I directly plug my computer into the cable modem, I am given a signal and I can post this thread. I have upgraded the firmware, reset the router manually, unplugged it for about 15 minutes (think it clears the cache?) then replugged it in and also have reset to factory defaults to no avail. So, to sum things up, I do get an internet signal, but for some reason the router doesn't want to distribute the signal. I fear that it's being a hog and using the internet for its own benefits (sarcasm! )

No. You are the hog. Your computer which works directly on the cable modem hogs the connection. Try the other computer directly on the modem and most likely it won't work either.
You cable ISP locks the connection to the MAC address of the computer.
Depending on the ISP and the cable modem there are different ways to clear it:
* call the ISP while not connected or ask them how to do it.
* reset the modem.
* unplug the modem from power. (of course restarting it with the router connected)
* turn off the modem for the night.
If nothing works, you can also try the MAC address clone function in the router. Wire the modem to the internet port of the router. Wire the computer which is able to connect to the internet through the modem to a numbered LAN port. Now open http://192.168.1.1/ The MAC address clone should be a subtab on the main Setup tab. Clone the MAC address of the computer. It should be easy simply by pressing the button to clone "this" computers mac address. Don't forget to click on save settings afterwards. Then check the status page. The status page now should show you the MAC address of the computer. It should also connect now.

wireless laptop - auto ip
I've had this router for about 3 weeks and every 5 days or so my internet connection is lost. the laptop and desktop are still connected to the network however any internet connectivity is lost. a reboot of the router and pc are necessary. i also notice when this happens my gateway address (on the status section) changes.
my question is why is this happening? it's so frustrating to have to restart the router/modem every week. is my setup correct? i like to have a static ip so i can port forward to host pc games and use remote desktop while i'm at work just because i'm a geek. does anyone have any insight? let me know if you need more information.

reset the router to factory defaults...check whether the firmware is upgraded to 8.00.2 or not .. if not , try upgrading the firmware again

WRT54GS with Mac OS 10.6.8 and RCN cable modem not working

Hello,
I have a Linksys WRT54GS, version 6 with Mac OS X (version 10.6.8) hooked up to a Scientific Atlantic cable modem, with RCN as the ISP.
Recently, RCN had some network issues, and so I had to power down and reset my modem. The modem is working fine now -- no problems at all when the Mac is connected direclty to the modem.
The router's network is OK in that I can connect the Mac wirelessly to the network, but I can't connect to the internet through the router (through neither the wireless or wired connection).
I have downloaded the latest firmware update for the router, following the Linksys site instructions, but this has not helped me solve the problem.
Does anyone have any advice as to what I should do? I did call Linksys tech support on the advice of RCN, and they said that the router does appear to be working (power, WLAN, and Internet lights are on), but they would be charging me nearly the cost of a new router to fix the problem.
Any advice would be appreciated!

Since you upgraded the Router WRT54GS with the latest firmware so once reset the Router and power cycle the whole network… Then connect the Modem with Linksys Router on the Internet Port and then connect any one computer to any one of the Ethernet port on the Router [Numbered – 1, 2, 3 and 4]… Let me know the RCN connection is a DSL connection or cable connection…
So if you have a DSL connection you can refer to this link:
http://www6.nohold.net/Cisco2/ukp.aspx?pid=93&login=1&vw=1&app=search&articleid=4020&userrole=Linksy...
So if you have a Cable Internet Connection you can refer to this link:
http://www6.nohold.net/Cisco2/ukp.aspx?pid=93&vw=1&articleid=3686
As far as the wireless is concern:
# Open up the browser and on the address bar type 192.168.1.1 that will open up the Router setup page…
# Then Click on wireless Tab create the Wireless Network Name SSID and select the channel to 6, 9, and 11… Click Save Settings...
# Then Click on Wireless Security sub tab and select the security mode and provide the password as per the requirement… Click Save Settings...
After doing the settings try to connect the preferred network on the wireless devices and check the connectivity….

WRT54g on Mac PowerPC G5. Not Working.

Hey Guys n Gals;
Running Comcast Business Class in my restaurant. I have a Mac Pro PowerPC G5 tower running OSX: 10.5.8. The Comcast guy hooked everything up along with the WRT54g i found in the basement (previous owner). Everything worked well, he programed the router through his internet pad; never touched my Mac. All of a sudden my power outlet in which my modem and router are connected reset themselves. I reset them back on, however, my router Never worked again. My mac is directly connected to my modem, not router. I have it hooked up on LAN #4 (light turns on), however, after the outlet reset, the router wont even show up on my Modem's LAN. I cant open it open it on my browser, 192.168.0.1, or 1.1. I try the 30-30-30 reset, nothing. While looking for my own remedy, i think i downloaded the new firmware to my mac, nothing happened. Any IDEAS??? Please, need wifi!
Thanks in advance.
Uriel

Here is the bit confusion, modem is connected on which slot of the Router? Here is the connectivity first of all connect the Comcast modem to the Router on the Internet port and then connect the computer with any one of the Ethernet port of the Router [Numbered 1, 2, 3 and 4] then the light status on the Router as well as check the IP address…
You can find your IP address from the Mac System Preferences:
From the Apple menu pull down “System Preferences”
Click on the “Network” preference pane
Your IP address will be visible to the right
Let me know what information that you get in that window….

Wrt54g Ver2 + Mac = Wrong Subnet

Come on Brainiacs, I know someone out there has some ideas - I googled and this has been happening, however, no solutions have been published. Afraid of a challenge? too busy telling people that "admin" goes in the password portion? Sheesh I have a functioning wireless network, I brought two Macs onboard (G4 Imac /OS 10.4). I can connect to the wireless network, however, while using DHCP I am issued the wrong subnet (255.255.0.0), resulting in a IPPA (169.x.x.x). Here is the odd thing, I was unsuccessfully working on a static IP setup on the Mac when I switched back to DHCP and it picked up the right subnet and viola it was working fine. I powered down and the next day the same thing, wrong subnet and I can't get it to replicate that scenario, if I could, I'd never shut it off. There has to be a fix for this, probably something simple, I am sick of googling, help me out would you?

I guess you have connected the WRT54Gs through their LAN ports and the internet port is empty. That's the way how you use them as access points.
If you connect them that way the gateway or router mode is irrelevant. The mode only works between the LAN and WAN. They did not design the WRT really for use as access point with an open internet port and therefore this is not documented in the help file. I would leave the setting on gateway as then it is a setting less to change back in case you must use it as gateway later again. If you use router mode, make sure RIP is disabled. The router is not working as router thus it needs no routing information...
Regarding your question: the answer is only the obvious one: except for the more extended configuration options in the WAP I don't think their is an advantage for either one.

WRT54G - Firmware problem - Wrong update of firmware

HI, I have a problem with my WRT54G V8 router.
I download a wrong Firmware and upgrade it.
After this my router never work again.
The PC can't get IP from the router.
I tried a lot of time to access to the web admin 192.168.1.1 and other IP and nothing happen.
I made a lot of reset cycles, with the procedures 30/30/30 or other with the reset button in combination with the power cord.
Exist any other possibility to recover my router.
Can I open and touch other button inside the board or something like this?
Or any other software...I tried the TFTP & other Windows utilities...
I am waiting for your help...
Thanks.

The network cable in the Internet place when I connect stay on without turning off.
And when I plug the network cable between 1-4 place I see that the light turn on/off like it is receiving information.
The IP address is not pingeable.
Cisco does not give another tool to recover it?
Do the upgrade via tftp again. Before doing it again do the following first:
Reset the router. Push and hold the reset button for 1 minute. After a minute, do not release the reset button from being pressed. Continue holding it and unplug the router's power cord for 20 seconds. After 20 seconds connect the power adapter to the router again while still pressing the reset button. When the adapter is plug in, wait for another 10 seconds and release the button. Ping the ip address of the router 192.168.1.1 using the command prompt.(remember the computer should be hardwired to the router and should be DHCP enabled).
If getting replies:
1. Set static IP, Subnet Mask and Default Gateway on the computer: IP: 192.168.1.10 DG: 192.168.1.1 SM : 255.255.255.0.
2: Force the card to 10 mbps half.
3: Perform tftp.
If getting rto:
1. Set static IP, Subnet Mask and Default Gateway on the computer: IP: 192.168.1.10 DG: 192.168.1.1 SM : 255.255.255.0.
2: Force the card to 10 mbps half.
3. Ping the router again and if you are getting replies already, then do the tftp. If not, you can try the steps again using another computer. If using another computer is not going to work then the router might be defective already.

WRT54G cannot save DHCP settings

Hi,
My WRT54G will not save changes to the number of DHCP users. I have a static IP address from my ISP and have all of the info entered correctly and can connect wirelessly to the internet from my laptop but not from my wired desktop. I'm guessing it has something to do with the DHCP settings.
On the router setup page it has the starting IP address as 192.168.1.1 (which is the IP address of the router and shouldn't be the pool's starting address) and the max number of users as 2. If I change the starting IP address to 192.168.1.2 it automatically sets the max number of users to 1. If I try to enter in any other values than those above for the starting IP address, it does not save the changes even though I get that page that says 'settings have been changed successfully' and the 'continue' button.
I am running Vista on the laptop, XP Home on the desktop and have an SDSL modem from my ISP. I just switched from a Belkin router to the Linksys & both pc's could connect before with the Belkin except it kept dropping the wireless connection on the laptop -- hence the reason for the switch to the Linksys.
I hope this makes sense to someone out there who can offer some assistance. I certainly do appreciate any help offered.

You need to reset the router to factory defaults, then setup your router again from scratch. If you saved a router configuration file, DO NOT use it.
To reset your router to factory defaults, use the following procedure:
1) Power down all computers, the router, and the modem, and unplug them from the wall.
2) Disconnect all wires from the router.
3) Power up the router and allow it to fully boot (1-2 minutes).
4) Press and hold the reset button for 30 seconds, then release it, then let the router reset and reboot (2-3 minutes).
5) Power down the router.
6) Connect one computer by wire to port 1 on the router (NOT to the internet port).
7) Power up the router and allow it to fully boot (1-2 minutes).
8) Power up the computer (if the computer has a wireless card, make sure it is off).
9) Try to ping the router. To do this, click the "Start" button > All Programs > Accessories > Command Prompt. A black DOS box will appear. Enter the following: "ping 192.168.1.1" (no quotes), and hit the Enter key. You will see 3 or 4 lines that start either with "Reply from ... " or "Request timed out." If you see "Reply from ...", your computer has found your router.
10) Open your browser and point it to 192.168.1.1. This will take you to your router's login page. Leave the user name blank, and in the password field, enter "admin" (with no quotes). This will take you to your router setup page. Note the version number of your firmware (usually listed near upper right corner of screen). Exit your browser.
If you get this far without problems, try the setup disk (or setup the router manually, if you prefer), and see if you can get your router setup and working.
If you cannot get "Reply from ..." in step 9 above, your router is dead.
If you get a reply in step 9, but cannot complete step 10, then either your router is dead or the firmware is corrupt. In this case, use the Linksys tftp.exe program to try to reload your router with the latest firmware. After reloading the firmware, repeat the above procedure starting with step 1.
If you need additional help, please state your ISP, the make and model of your modem, your router's firmware version, and the results of steps 9 and 10. Also, if you get any error messages, copy them exactly and report back.
Please let me know how things turn out for you.

DHCP conflict

I am running 10.4 server in an elementary school with about 100 computers, desktops and laptops, mostly running 10.4. The server was set up by a professional in the summer to run DHCP. A week or so ago, we lost our internet connection. It seemed the trouble was our sonic wall content filter so it was disconnected and the router reconfigured (not by me) to do DHCP. Now we have internet but it drops all the time. Clicking renew DCCP lease solves the problem but I assume there is a conflict between the server and the router. I tried disabling DHCP in the server and the router separately but we lost service again completely? Does anyone have any thoughts for a new person?

There isn't enough information here to be able to form an opinion, or at least, answer the question.
There are so many ways the network could be architected that it's hard to tell.
For example, what services (other than DHCP) is the server providing? Just directory service? file service? web service?
Is it acting as a gateway providing network service to the clients (so all clients talk through the server)?
That's important to know since it will affect how the clients connect.
In general, it shouldn't matter which DHCP server manages the network (and multiple DHCP servers are valid, too), provided they are configured appropriately.
You should really think about what your preference is - do you want the Mac to provide DHCP, or the router?
Once you decide that you can focus on configuring that device in the way that's appropriate for your network and disable the other completely.
