Linksys E3000 Connectivity Problems

[bmandel]

I am also having intermittent E3000 connectivity issues as well.  I have lost Internet connections for a short time on a few occasions, but my larger issue has to do with wireless printers going offline and being unavailable.  These printers obtain their IP addresses from DHCP.  On my previous router, I also used DHCP and have not changed any setting on the printers, other than a new SSID for the new router.  On the old router, I never had a problem.

When the printers go offline, if I view the DHCP table on the router, there are no longer any entries there for the printers.  The printers go offline intermittently and not necessarily when the DHCP lease expires.  In fact, I have seen the DHCP lease expire and a new IP address issued to the printer successfully.  I contacted Cisco chat support and really was not able to get to the bottom of it.  I am trying static IPs for the printers to see if that helps, but if the router has an issue, it will not "see" these printers anyway.

I tried DHCP reservations for the printers but that did not work either.  At some point, somewhat randomly, the printer loses connection to the network and goes offline.  The only way to re-establish is actually to restart router.  Turning off/on the printer does not necessarily work all the time.

Like your father, I work from home over a VPN connection.  I had to replace my WRT300N because it was taken out by a storm even though I had a Power Strip.  Anyway, I replaced it with an E3000.  Eveny since I replaced it, I have had issues maintaining connectivity over a VPN.  Over the WRT300N Router, my connection would stay up for the 24 hours duration until the session actually timed out on the VPN Concentrators.  Over the E3000 Router, my connection drops 8+ times per hour.  If ANYONE has a recommendation on how to resolve this issue, please post it as soon as possible and help us out.  Thanks in advance.

Do you have the Cisco Connect software installed? If you do, it would automatically  tell you that updates are available. Just download the updates and this should address the issue.

the new firmware makes it worse, DO NOT DO IT

People are blaming the connection problem on heat. 

That is incorrect. 

My problem was mainly on 5Ghz connections but I suspect is the same cause as everyone is seeing.

I had a chat with a Linksys tech this weekend that knew what he was doing.

After changing some settings it is working solidly.   No dropped connections at all.

Now it is a great product.

Tech support via chat seems very good.

smtguru,

Are you saying these are the wireless settings that the Linksys tech gave you after troubleshooting with them on dropped wireless connections overall, or are these settings for VPN stability?

I'm having trouble with a laptop that has ridiculously slooow response after getting connected to a VPN server using a wireless connection on my E3000.  If I connect the laptop to VPN via an ethernet cable connection to the E3000, VPN works perfectly, no slowness.  But if I connect wirelessly, it connects to VPN, but no go on opening files, nothing happens.  Laptop uses a Cisco Systems VPN Adapter and Intel Pro/wireless 3945ABG network adapter.

I'll try these wireless settings exactly, and if VPN is still borked, I guess I'll need to call tech support as well because this is just driving me crazy.  I had initially setup wireless settings of the E3000 exactly the same as I had on my wrt310n (where VPN connections wirelessly worked flawlessly), but VPN didn't work on the E3000. Something is buggy with a wireless connection to the E3000 and VPN access.  I have already upgraded to the newest firmware also, doing a 30/30/30 reset both before and after the firmware upgrad.

Title of this thread is Linksys E3000 Connectivity Problems

These settings were from Linksys for the overall dropped wireless connections.

VPN may be a different cause.

Good luck

smtguru,

Thanks for clarifying.  That's what I thought, but I just wanted to check because someone had mentioned VPN connections in this thread also.

Hi Argyll...

I noticed your using the same wireless card as me....  I have an x60 Lenovo with the same card...

I used the recommended Linksys Tech user settings listed here and also adjusted my card to dedicated it on the 5ghz band.

You can do this in the Hardware Profile area under Computer Manage - Xp or Windows7.

I use AT&T VPN - AGN client for work and this is working ok....

I will be testing this more in the next few days and will report back...

Regards;

H.
