Linksys WRT400N - Connection To Internet Switches To Offline

I purchased a Linksys WRT400N on 2/3/2010 from OfficeMax.  I finally got around to setting it up last week.  The setup was relatively painless but not without issues as I know there was going to be something not quite right.  The WRT400N is replacing a WRT54G which worked flawlessly for 3+ years.  The WRT400N is running in 2.4G mode now. We bought this router for it's media streaming capabilities which we have yet to hook up.  We will be using a WD Live TV for our audio and video streaming using a Linksys USB600N.

 

The issue we are experiencing is that at the same time each day ... approximately early evening ... 6pm - 7pm ... our FireFox browser says that it's in Offlline mode.  When this happens, we can't connect to the Internet at all even though the connection icon in the lower-right hand corner says it's connected.

 

Looking at the router itself, everything looks to be connected and all appropriate lights are on and steady.  The only way I can reconnect to the Internet is if I do a hard reboot on our Dell Inspiron E-1505 laptop (running Vista 32-bit).  I can't do a reboot since the computer just hangs when trying to reboot ... it's like the router is locking up the laptop.

 

I am running the current version of firmware.  I have reflashed the router.  I have done the unplug bit ... nothing is helping.  The router is not overheating and has good ventilation since it sits on a rack that has slots.  There is nothing else around the router.

 

The one thing I notice on the WRT400N device web page is the Client Lease time.  When I log into the device web page, the default value for this is set to 1440, which is the total minutes in a day.  When I change it to 0 (which was the setting in the old router) and click Save Settings, it saves it.  However, when I log into the device web page at a later time (i.e. 10 minutes later or more) the value is back to 1440.  Is this behaving normally?  What other settings should I check?  I already changed the MTU value to 1492, 1365, 1350.  I am not noticing a difference there.

 

Any help or suggestions would be appreciated.  At this point, I am at a loss.

Re: Linksys WRT400N - Connection To Internet Switches To Offline

1. If Firefox says it's in offline mode you have to switch it back to online mode. It will go into offline mode if there is no network connection at all.

2. The computer should never hang because of a non-working network connection. If it does, there seems to be something very wrong with your computer. The router can't "lock up" the computer.

3. Do you have another computer to check the status of the router? i.e. a computer wired to the WRT, check the status page in the web interface http://192.168.1.1/

So far, it sounds like a computer problem. Something going havoc on the computer at that time. The router can't do that. If it can then it is a bug in the network drivers on your computer. The computer should run regardless of what the router does or does not...

Re: Linksys WRT400N - Connection To Internet Switches To Offline

Thanks gv.

 

How do I switch FF to "Online" mode?  Yeah, there is definitely no internet connection.  I can't connect with any browser.  It's like the connection is dead, but there are no physical signs that is says it's dead other than I can't connect via a browser.  All indicators make it look like I am connected.

 

Yeah, I will check the drivers for the wireless card I have.  See if there's an update for it.

 

Yeah, I can use my work laptop to try and connect (i.e. a wired connection)  to the router when we are experiencing the "offline" issue.

 

Right ... sounds like a computer problem right now.  That is my thinking.  I wonder if going to Windows 7 would help or if this is more of a hardware / driver issue.

 

Thank you again for your help.  Do you suggest any specific settings?  Do you know anything about that Client Lease functionality and what it should be populated with?

 

Thanks.

When it happens again open a command prompt window and enter "ipconfig /all". Copy the full output into your next post.

I did down load the latest Intel wireless card drivers straight from the Intel PRO/Wireless web page this past weekend.   So far, there has not been any lock-ups on the internet connection.  We'll have to continue testing but so far so good

 

Thanks,

 

Rick

This looks like a driver problem. In that situation you could check the device manager to see if the driver indicates any problems.

Right.  That is what I thought as well.

 

I downloaded the most current Intel PRO/Wireless 3945ABG driver from the Intel website and not Dell's.  Dell does not have the most recent driver posted.  Intel recommends that you download the driver from the laptop manufacture support website, but that's not an option for me since Dell does not have the most current driver set.  Crazy!

 

So I downloaded the most recent driver from Intel and installed it without any issues.  The wireless driver I had was about 2-3 years old.

 

I will keep an eye on it, but so far so good and the connection seems fast.  

 

Thanks for the help and advice.

 

Rick
