#21284: EA3500 (Audi Kirkwood) wifi unstable. ------------------------+--------------------------------------- Reporter: anonymous | Owner: developers Type: defect | Status: new Priority: normal | Milestone: Designated Driver (Trunk) Component: kernel | Version: Trunk Resolution: | Keywords: ------------------------+---------------------------------------
Comment (by lordgilman): I've been working with the author of the EA3500's wireless driver on the linux-wireless mailing list. You can see the latest message in our correspondence here: http://marc.info/?l=linux-wireless&m=146752644907945 I've recompiled hostapd with full debugging support and captured the logs in that email for when the disconnects happen. No drop ever looks exactly the same but they all look like the WiFi device is unable to respond to the EAPOL message in time. This would explain why certain devices work fine on the same hardware while others are perpetually dropping connections, and why molocho's findings in comment 32 show that switching to a quiet channel doesn't help out here. The timeouts for all of this stuff are hardcoded in hostapd, in src/ap/wpa_auth.c. I am tempted to get a patch to change these, but the fact that they're not configurable at runtime makes me a bit wary that there might be a good reason for those constants. I'd appreciate it if anyone from the OpenWRT project who's familiar with the workings of WPA could give some opinion here. If this patch isn't a bad idea it might be a good idea to ship the Audi Kirkwood binaries with a patched hostapd. -- Ticket URL: <https://dev.openwrt.org/ticket/21284#comment:33> OpenWrt <http://openwrt.org> Opensource Wireless Router Technology _______________________________________________ openwrt-tickets mailing list openwrt-tickets@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-tickets
