I have noticed that some hotspot clients are blcaklisted with the OS at times . the Hotspot (DHCP server) will issue an IP to the client but will not allow traffic to pass through it from the MAC address untill i do a reboot of the OS. Has anybody realised/exprienced this?
Yes..
But I always attributed it to too much noise in the area and/or board could not handle the load.
I switched to a different card and updated the board and/or installed a lower db antenna and usually that fixed it.
