[Bug 1221857] Re: Wifi slowly degrades until no data transfer
Also it is my understanding looking at Redhat Bugzilla and Launchpad
that Intel still has not solidly implemented 802.11n in the iwlwifi
driver for all cards. Although I have tweaked with module settings such
as disabling N I'm unsure if the issue is even related since the
slowdown seems to happen even with N toggled off.

Title:
Wifi slowly degrades until no data transfer
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
My wifi has been slowly degrading at random times to the point of no
data transfer but network-manager still shows connected. Only thing
that resolves it seems to be manually disconnecting from wifi AP via
network-manager and reconnecting also toggling N off in iwlwifi seems
to have some effect (maybe coincidence though)
I have ruled out the issue being a result of interference by checking
signal quality (iwconfig) when it occurs and my cable modem is online
with no issues and so is Wireless AP and other devices do not have
this issue.
