I am using a TP-Link Wireless ADSL2+ Modem router with Ptcl DSL. My internet randomly stops working and when I go to the device page 192.168.1.1, instead of TP-link's page the device page of ptcl's tenda device opens up. At other times 192.168.1.1 leads to the tp-link page like it should and those are the times the internet is working. So what the heck is going on??
