I've been using the TP-Link WR841ND wireless router for the past 3-4 months and it has worked perfectly, until last week when it suddenly stopped connecting to the internet.
(I'm still able to connect to pccw netvigator using the modem).
I've tried resetting, restore factory settings, reinstalling, replugged, changed cables, changed IP address of router, cloned MAC address but to no avail. Is there anything else I can try? Thanks for any help.
