I have deployed CeroWrt 3.10.50-1 on two WNDR3800's at a hospitality = business nearby. These routers have worked fine in my house in the past. = WNDR3800 #1 talks to my DSL modem (wifi disabled), and WNDR3800 #2 has = its WAN wired to the LAN side of #1 (routed, no NAT). I also have a = third router (Netgear something or another, running stock firmware and = NAT) with its WAN port wired to WNDR3800 #2 LAN, at the far end of the = property. While in operation, they work as expected, and fq_codel is = doing its job (also as expected). The setup - all dashed lines are = Ethernet: [ Internet ] --- [Fairpoint DSL Modem] --- [WNDR3800 #1] --- [WNDR3800 = #2] --- [Netgear ?]=20 The problem is that the Wifi locks up on either/both WNDR3800's after a = while (a day or so). Guests complain that they cannot connect to the = wifi. If the innkeepers reboot the router, Presto! it's fine for a while = longer.=20 I have only been present once when it was in the stuck state, and wired = access to/through the WNDR3800 #1 was fine. My Macbook was *not* able to = get a connection through wifi, but both Wifi Explorer on the Mac and = Wifi-Analyzer on android could see a healthy signal level (and no = overlapping channels) on the expected channel. Here's the wifi setup: - I only have one interface on each of the 2.4 and 5 GHz radios. (I turn = off babel and the other wifi channel) - All SSIDs (on each of the routers) are the same string "Loch Lyme = Lodge" -The wifi channels are different (1, 6, 11 for 2.4GHz, 36 & 44 for 5GHz) = for all the routers My questions: - Any thoughts about what might be causing this? - What should I look for (log files, symptoms, etc) next time I get the = word that it has happened? Many thanks! Rich
