Unable To Renew Ip Address (event Log)

[ace]

Hello,

 

I am running a Linksys BEFSR41 router with the DHCP enabled.

I have two XP Pro boxes connected to it and on the other end

is a cable modem. I am getting the following error in the event log on both PC's. (see below)

However I am getting a new IP lease despite these errors. I get a error telling me that the lease has expired then 2 seconds later a new lease is obtained.

 

Any idea if this is normal or is the DHCP part of the router not working?

Any help would be appreciated.

 

 

Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address XXXXXXXXXXXX. The following error occurred:

The semaphore timeout period has expired. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

 

 

Your computer has lost the lease to its IP address 192.168.200.25 on the Network Card with network address XXXXXXXXXXXX

 

 

Thank you so much TCH family Rock Sign

I don't have any idea about this but I'm going to move it to a more appropriate forum, so that I can feel at least somewhat useful in helping you to get a response.

Hi ace, there is an option to set the lease time to never expire. I don't know exactly where it is at the moment and don't have the time (working) to research it for you. But its not critical and unless someone else comes along and gives you instructions I'll look it up when I get home later this afternoon.

 

DHCP will assign an IP to each PC that joins the network and its setup with a "lease time", a set time when it will expire and the IP will be lost. The PC's will then request for a renewal and either get the old IP renewed or a new one assigned.

 

It sounds like yours are being renewed and these error messages are just informative.

 

If you know how to log into your router, look for the option for DHCP and see if you can find the "no expire" and turn it on.

ace, I done a little looking around and from reading the routers manual I do not see a setting for no expire. But I have found that the router you are using has had issues. I would suggest you go to the Linksys website and update the firmware.

 

Instructions and downloads can be found here.

I was able to renew the ip address just fine in a command window using the

ipconfig /renew command. It renew and windows gave me no errors.

I am wondering if this is a microsoft issue.

 

Any thoughts?

If your dhcp clients are configured as default , and they (and the dchp server) are never powered off, then they should never lose their leases. In fact, the MS dhcp clients are configured to try to renew their leases starting halfway through their current lease. This gives them plenty of time to renew, should the DHCP server be unavailable for some reason.

 

I have seen some posts referencing problems with DHCP and software firewalls (Norton Internet Security specifically).

If you are running one, try turning it off temporarily to see if the errors go away. You may need to configure the FW to be less stringent with DHCP traffic. I personally don't use software firewalls, so I'm afraid I won't be of much assistance there.

i have the same router and the best thing is to set them to static ip's using 192.168.xx.xx

 

x's what ever you want up to 3 charectors each for ex 192.168.215.123 using this method

 

it is easy to trouble shoot and since you only have two it is a snap

 

not to mention it is easier to punch holes in your firewall to allow programs to work right and then close it when your done

 

plus you will all ways know your comptuters ip

Mr Lucas,

 

Does your router have the same issue?

 

Regards

[mr_lucas]

no it does not for the reason that the ip's never change

 

 

but if i remember if you have Connect on Demand: Max Idle Time checked it will generate a error like the one you have but i am not sure anyways i have it unchecked

 

oh check to see if you have asigned a ip to the system with out a subnet mask

 

and by the way how knolegable are you in this area because i dont want to give you simple things to do that you allready know like the back of your hand

 

if this insults you am am sorry and you dont have to anwser

 

plus i need to know what you have like router, modem, ISP and if your using web IP's or lan ip's

Hi guys!

 

I'm wondering if you are utilizing any Norton software that uses live update. I had a similar issue and discovered an apparent link between Live Update and connection problems. I first shut off the automatic Live update feature and all worked fine. Then, I went to Symantec.com and followed their instructions for configuring Live Update for working with a cable modem, and my problems seem to be gone.

 

The article on their site is in their knowledge base. Document ID: 2000071310294913.

 

Basically it says

 

click 'start', 'control panel', 'switch to classic view', then double click 'symantec live update'.

 

Then click the ISP tab.

Click 'Internet options in control panel', 'configure', in the new Windows Internet Properties box click 'LAN settings', click 'automatically detect settings', then click all the ok's to finish. I suggest a reboot after that.

 

Hope this helps

Back to the original topic!!!

 

Madmanmcp suggested a firmware upgrade. I concur, as the upgrade he linked to is specifically to fix a dhcp renew failure bug. Of course in true Linksys fashion, there are no details beyond that, so it is unclear if the bug is in the DHCP server (serving IP addresses to LAN clients) or in the DHCP client (getting DHCP address for WAN interface from Cable/DSL DHCP server).

 

Anyhoo, having the latest firmware *generally* can't hurt.

Hello All,

 

Linksys confirmed with me that the router is bad. They are not sure but they believe the firmware chip could be bad. I downloaded their latest firmware and followed all their steps to resolve the issue with no success.

I returned the router as it was new and got a d-link 604. Everything including the DHCP server works great. Linksys was very unprofessional in terms of their technical support folks. They where hard to understand. (did not speak English very well) and never answered the emails that they asked me to send to them regarding my issues. I would not recommend Linksys at all.

 

Mr Lucas, no offence taken...I consider myself (in my opinion) in the know about technology as I work with this stuff in my employment. I am a Technical Analyst.

But I will be the first to admit I don't know everything.

 

Thanks for all your help.

Thanks for the update and glad you found a "fix".
