Re: E3000 Wireless slows down until a reboot

skiingj1,

 

I was experiencing the same slow down you mentioned with my E3000 as well.  I also have Comcast.  Within a few days of having the E3000 router,  I discovered the slow down, I rebooted the cable modem and the E3000 router and then one at a time.  The E3000 seemed to be the culprit after a few test runs over the next few days.  I did a search on the net about complaints on having to reboot routers (Linksys 610N, I believe).  I discovered that someone had suggested lowering the MTU to 1350.  I entered the web interface (I didn't install the software) and set the MTU tab to manual and set the value at 1350.  I'm going on about two weeks now and have not had to reboot the E3000 again.  I just tested it again before posting this suggestion and it is 26.99 Mb/s and 9.36 Mb/s.  The ping is 25ms.  I hope this works for you as well. 


 

Thanks for this tip. I tried this a week ago and no slowdown since (up to then was having exactly the same problem as others on this board). As of this morning still running at 50+ mbps upstream and 5+ mbps downstream with no reset for a week :smileyhappy:.

I confirm the problem, after 48 hours of testing the slowdown appeared again. I will test the MTU fix now.

Just changed the MTU to 1350. Starting a new test at 20:15 local time. Below are my speeds at this moment:

Re: E3000 Wireless slows down until a reboot

Nope... It didn't worked. Right now I was getting 26Mb/s dowload. I rebooted the router and get back to 37Mb/s.

 

Any sugestions? Or will we have to wait for a firmware update?

Well, they didn't fix it in the first update, so I guess we'll just have to wait.

I found another thread where people with the WRT610N router was having the same issue, and apparently turning off UPNP solved the problem for them.

The next time my connection slowdown I will try this.

It's just hard to live without uPNP... hopefully they'll actually fix the problem.

It's 30 hours since I turned UPnP off and my speeds are still normal.

Ok, for grins lets see if the bug actually is in the uPNP functionality, or related to it.

 

Here is my current speed with uPNP off.  Let's see if it degrades.
