I seem to have been having this problem off and on for a while, however it became much worse recently, with my ping exceeding 1000ms, right now it's averaging about 500ms, which is much better than it was, although that's when pinging my alpine box (which acts as the gateway/router/firewall for my network) which should be much lower (~1ms). Checking the logs, I realized the kernel is throwing the same error related to the rt2x00queue_write_tx_frame symbol, as follows: Jan 23 18:40:59 security kern.err kernel: [16896.045803] ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2 Jan 23 18:40:59 security kern.err kernel: [16896.045809] ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2 Jan 23 18:40:59 security kern.err kernel: [16896.045815] ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2 Jan 23 18:40:59 security kern.err kernel: [16896.045821] ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2 Jan 23 18:40:59 security kern.err kernel: [16896.045827] ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2 Jan 23 18:40:59 security kern.err kernel: [16896.045833] ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2 Jan 23 18:40:59 security kern.err kernel: [16896.045839] ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2 Jan 23 18:40:59 security kern.err kernel: [16896.045845] ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2 Jan 23 18:40:59 security kern.err kernel: [16896.045850] ieee80211 phy0: rt2x00queue_write_tx_frame: Error - Dropping frame due to full tx queue 2 I am using the linux-grsec kernel, and this occurs whether I'm using the kernel from stable or edge.

I have tried to use every patch I could find on the subject, and every one I found seems to not be compatible with the GRSEC patches or other patches included in these kernels. I am ready and willing to test and build any patches that anybody can provide. Note: this seems to be related to multi-BSS, I just tested on my public network and it pings at ~50ms Any assistance in resolving this issue would be greatly appreciated. --Matt --- Unsubscribe: alpine-devel+unsubscribe@lists.alpinelinux.org Help: alpine-devel+help@lists.alpinelinux.org ---
