upgrade

I recently upgraded my kernel from 2.6.31-gentoo-r6 to 2.6.32-gentoo-r7. In both cases, I configured everything manually. However, since the upgrade, my wireless card appears to be on the fritz. It will connect to networks just fine, and remain connected, but can only access the internet (and other hosts on the network) for about 3 seconds after connecting. Reconnecting to the network appears to fix the problem... for another 3 seconds or so.

The problem is "solved" by booting into the older kernel. The relevant lspci entry is

02:00.0 Network controller: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection

I'm pretty sure I have the correct drivers enabled in the kernel

Device Drivers --->
    Network device support --->
        Wireless LAN (IEEE 802.11) --->
            <*>   Intel Wireless Wifi
            [*]     Enable LED support in iwlagn and iwl3945 drivers
            [*]     Enable Spectrum Measurement in iwlagn driver
            [*]     Enable full debugging output in iwlagn and iwl3945 drivers
            <*>     Intel Wireless WiFi Next Gen AGN (iwlagn)
            [*]       Intel Wireless WiFi 4965AGN
            [*]       Intel Wireless WiFi 5000AGN; Intel WiFi Link 1000, 6000, and 6050 Series

I tried with the other intel drivers enabled as well (iwl3945) and no difference. Is there something stupid I'm missing? Is there something I have to recompile after upgrading the kernel (a la nvidia)?

Thanks
Mala
