Hmmm. That file was not in that folder on my laptop, but I have the same issues: limited to wireless G only, with an Intel wireless card:

Any update on the update from Intel?
I just discovered today that I had my AP set for G only. I set it to N also and for the rest of the day, I've had very uneven results. At times throughput is stellar - even better than my 100baseT LAN. But more recently the WiFi connection has been down more than up. I frequently can't even load a web page before it stops working again. I don't see any messages hinting at the problem in the logs.
I'm running 10.04 which uses firmware /lib/firmware/iwlwifi-5000-2.ucode.
I've added the file listed above (/etc/modprobe.d/intel-5300-iwlagn-disable11n.conf) with contents:
to revert to G only.Code:options iwlagn 11n_disable=1
... Actually, that did not work. Neither did the following commands:
Code:sudo rmmod -f iwlagn sudo modprobe iwlagn 11n_disable=1
I guess I'll need to disable N on the router again.
I wonder what the fix for 10.04 was and if I'm experiencing the same issue.

This works for me, my network is set to N only, no G. Without # it sees the network but will not connect.Code:# options iwlagn 11n_disable=1
I had some problems with the driver supplied with Ubuntu 10.10 but after switching to the latest developer version (by installing apt://linux-backports-modules-wireless-maverick-generic) it works fine!
wlan0 IEEE 802.11abgn ESSID:"XXX"
Mode:Managed Frequency:2.442 GHz Access Point: 00:1A:70:XX:XX:XX
Bit Rate=144.4 Mb/s Tx-Power=15 dBm
I don't believe they disable it by accident. I have 4965AGN card in my laptop and I tried to enable it by deleting that .conf file. It was fine for a while, but I had intermittent lock downs. I disabled N again, no problems.. runs smoothly..
Thanks for this, I was pulling my hair out trying to figure this out.

thanks for this thread, I have tried loading the module like described in page 1 "sudo modprobe iwlagn 11n_disable=0" and it is definitely faster if I do an internet speed test at www.speedtest.net i get roughly 40mbs down speed, where when I was on G only I would get about 10mbs down speed
dont know how "stable" its going to be as its only been 10 minutes so far, but its nice to be able to use most of my 50mbs broadband connection when on the laptop.
anyone know if Intel have released a updated revision of this firmware? and if they have will it be in 11.04?
currently I have 2 access points in the house, one that is B/G mixed and the other that is N only, because if I had the main router running NG mixed as soon as a G device would make all connections G speed.

Great news *Sarcasm*. Apparently intel will not fix the issues with wireless n with "legacy devices", including the 4965agn:

It will be very difficult to add the same firmware fix for legacy devices
including 4965. I am really sorry about it.
Thanks

All I can say in response....epic fail Intel, epic fail!
