Subject: iwl4965 on Compaq 8510p wireless speed very low, unusable
Date: Thu, 6 Mar 2008 15:20:38 -0500 [thread overview]
Message-ID: <c4aed99f0803061220y40628cdxc8c2a4a0d2cac89f@mail.gmail.com> (raw)
Tried many combinations of kernel (2.6.21 to current 2.6.24.3),
several combinations of mac80211, iwlwifi and iww4965 microcode,
including latest stable (1.2.0) and dev versions. Still can't get
past about 30KB download speeds. Access point is Linksys Wireless-B -
other machines on same network can get 10-15 times that speed w/ a
variety of adapters.
I've enabled logging in kernel config, but logs don't reveal anything unusual:
$ dmesg | grep iwl4965

(Gutsy Gibbons stock kernel)
After a couple days of searching (Google, bughost, etc) I've noticed
others with similar problems, but never came across a resolution. Bug
1481 is similar, though not exact. Performance is acceptable under
WinXP (400KB+)
Is this a configuration issue or a genuine bug? Any help would be
greatly appreciated.
I'll be happy to enter a bug report, and assist in any way I can
(testing, etc) to help reach a resolution.
