I have the most bizarre situation that has started over the last 2 weeks. I have an RB4011 connected to CR328-24P that connects to 2 GWN7660 APs. Most devices are then connected via wifi, however, I do have a couple servers and a couple ethernet devices. Randomly my device (WIFI ONLY) will just no longer have network access. I can see my WIFI SSIDs and connect to them, but I dont get a valid IP (169.x.x.x) So I cannot connect administer anything on my network to look at anything when it happens from that device. I can plug into ethernet and immediately get a valid ip and see everything, and everything seems to be operating properly. Then if I try to switch back to wifi, I cannot get an IP again. And not all WIFI devices will fall off at the same time, it may only be 2 or 3 devices that drop and just cannot get an ip after that.
I can cycle the power on both ap’s and usually that will pretty quickly fix everything. But it’s almost like some devices cannot reach the DHCP server on the router, or are finding another DHCP server. But if I release and renew an IP right now, it will not have an issue. I’ve checked the LOGS section on the router, but the only thing I see related to DHCP is designments and reassignments. Even my devices with static dhcp reservations have the issue. I’ve tried updating all firmware of the ap’s and router/switch, but It was not an issue for several years until just the 6th or 7th of October. What am I missing?
It seems you’ve pretty much ruled it to be WiFi devices. It is likely not the MT kit doing this but the way the WiFi AP’s are handling it. You have said cabled is fine so the only “other” possibility is the device(s) giving out WiFi.
I agree, thats what so bizarre, but the problem is, the SSID never goes away, I can swap between the 2 advertised SSIDs , but neither will give me an IP when connecting. I can connect to the APs when this is happening from another device and there doesnt seem to be any issue, its almost like the AP doesnt really understand how to let the router give it an IP. And If I try and give myself a static IP on the same subnet, it doesnt help, I cannot get to anything still.
You could try Packet Sniffer on the RB, see whether anything’s received from your static IP. Try the AP directly connected to the RB to rule the switch. Or try a different sort of AP, since that’s almost certainly where the issue lies.
Do you do anything “special” like VLAN? I have had Grandstream, only had some “specialities” while using VLAN’s…and I do that a lot. Can you share your (MT) config just to make sure there is nothing in there?
