Fixing dropped wireless connection for Linksys E4200

I've been going quietly mad trying to fix a constant dropped connection issue with our Linksys E4200 router. There's lots of advice around tweaking  the MTUs, upgrading firmware and disabling UPnP (a good idea anyway) but none of this helped at all. The connection just continually dropped, eventually came back, dropped again, ad nauseam.

The fix was to change the 5GHz and 2.4GHz networks to use different network names (SSIDs).  I then connected to the 2.4GHz flavor and the connection is now solid.

I guess the problem was that by sharing the SSID devices would keep switching between the networks whenever they got the chance to connect to the juicy 5GHz flavor. The 5GHz network is flakier (higher frequencies having less range) and so the constant dropouts.

I had the same problem - devices connecting over the wireless connection would disconnect occasionally. I tried giving the 2.4 GHz and 5GHz channels different names, and the problem seems to have gone away.

Unfortunately my connection still drops randomly despite trying the above.

my connection keeps dropping even hard wired, router reboots randomly.

Has anyone had issues with this router and the new windows 10 upgrade? I now keep getting dropped or get a "limited" and have to do a windows troubleshoot to temporarily fix the problem for 5 min until it drops again. Please help! (Besides telling me to get a new router :) )

Hey Mark, I was also going through the same problem with Windows 10, then managed to solve as follows:

Applications & Gaming -> QoS -> WMM -> ENABLE IT

Administration -> Management -> CTF -> DISABLE IT

...and it's been a month and is working smoothly!

I hope this helps!


Applications & Gaming -> QoS -> WMM -> ENABLE IT

Administration -> Management -> CTF -> DISABLE IT

It works. Thanks


After having a brand new Surface Pro constantly crash my network by causing the router to reboot, Mark's solution is the only thing that saved me from purchasing a new router. Thank you Mark! This is THE solution to the problem.

Applications & Gaming -> QoS -> WMM -> ENABLE IT

Administration -> Management -> CTF -> DISABLE IT

*NOTE: I only had to adjust the CTF setting in my setup.
