Comment 26 for bug 836250

I'm also seeing very slow speeds with Wireless-N using an Intel Advanced-N 6205 adapter, after updating to Oneiric (did the update about a week ago, before the final came out). Have applied all updates. Tried to create the file Alex mentioned above, but it didn't seem to improve things.

I'm getting about 20 Mbps from my ThinkPad running Windows 7 and just under 4 Mbps with Oneiric from my Dell Latitude e6420, connected to the same router.
