Having an issue with my Ubuntu 9.04 notebook + Intel 4965 wireless card. If I connect to A/B/G wireless networks, the wireless card works perfectly. However, if I connect to a WLAN with 802.11n support, the card gives me trouble. It usually connects just fine to the N network and gets a DHCP address. It will pass traffic for a minute or two, then just stall. I have to cycle the wireless switch and force a reconnect to get traffic flowing again.
