Alright, this one has got me completely stumped. Among other devices, I have three computers currently connected to the same wireless router:
One of them is connected through ethernet and has internet access.
One is connected to the wireless network and has internet access.
The third, despite having no problems connecting with wireless or wired networks in the past, cannot establish a connection with the wireless network. After connecting an ethernet cable, it had internet access for a short time. Now, despite the network still showing a connection and internet access, any attempt to actually access the internet fails.
I've tried all the basic stuff like reconnecting cables and resetting routers with no change. Any insight into what's going on here and how to fix it would be greatly appreciated.
