Situation:
There are way too many 2.4ghz networks in my apartment complex, so the 2.4ghz performance is pretty terrible even in a small apartment. To avoid problems with some devices, I've separate the SSIDs into two separate networks so I can be sure what's on what.
Just this morning I lost access to the printer (on the 2.4ghz), but only from the 5ghz network. This has happened before and eventually after much fiddling got it back for a while, but now it's busted again. Obviously tried just a reboot of the router & printer & devices.
The weird part is, I can see the printer from both networks in the arp table (from my Mac). I can even ping it from both networks. But if I try to connect to one of the ports (like 80 for the integrated web server), it times out when I'm crossing the bridge . As soon as I change to to the -2ghz ssid, everything connects fine.
I can replicate this trying to get to my iPad when I run a little tcp console server on it. when the iPad is on 5ghz and the Mac is too, I can connect just fine, but I can't connect to the tcp port as soon as I change the Mac to the -2ghz network. So it's not _just_ the printer. But unfortunately I can't replicate on 2 Macs running tcpdump to see what's happening....they connect fine in that case. From the sender side the first packet looks identical...link level send to the MAC address for the printer in both cases, there's just no response when it crosses the network.
I feel like it's maybe the router getting confused about which band a device lies on once the device list gets big enough, so I think I'll try clearing the device list and see if that helps, but man I'd really like to see some logs or be able to troubleshoot the actual "wire-side" of the 2.ghz network. Anyone seen anything like this with the Pace before?
