(C6250-100NAS) Slow http traffic

My setup was working fairly well for about six months until http traffic came to a crawl this week.  All clients behind the router have very slow web access over http (essentially unusable), however https access is just fine.  Web access through VPN is also fine.

 

Speedtest results from mobile devices running the speedtest app show expected speeds (>50Mbps).  The speedtest website can't even load on the laptops.

  

I tried to disable all firewall settings in the router, but they have made no difference.  I tried changing the DNS servers to google and openDNS with no help.

 

I have factory reset the router three times already.  The first time, it seemed to help for about 30 minutes before http bogged down again.  The factory reset did not help the second and third times.

 

Are there any other router settings or diag tools that might help isolate the issue?

    Hello Tlee

     

    First I would check your cable connection if your modem on a splitter if so try removing that and go directly to the wall. If that was not the issue you might want to do a ping test to check and see if you are having packet loss. it could be some bad connection from your ISP out to the internet. Try this website to test.  Last thing you can do is contact your ISP to make sure the connection is good and there is not high traffic happening in your area.

      Darren,

       

      Thanks for your thoughts.  I did check the coax and tightened it for good measure.  Unfortunately, pingtest was not reachable because of the problem symptoms.  I had Xfinity send refresh signals a few times, but it had the same result as the factory resets -- the first time helped for about 30 minutes, but subsequent refreshes did not help.

       

      I rented an Xfinity gateway yesterday to help isolate the issue.  I'm getting smooth performance with the Xfinity gateway so I have to conclude that the C6250 is failing on me.

       

      The C6250 2.4GHz network traffic bogged down about a month ago (while 5GHz continued to operate normally) so I assumed that it was a defect isolated to the 2.4GHz hardware.  I got around it by hooking up a travel router AP for 2.4GHz access.  That setup worked well up until this week.  It feels like whatever defect was afflicting the 2.4GHz network has now crept into the 5GHz and wired networks.
