Just today I had set up a LAN/LAN AP for my housemates upstairs as their internet kept dropping out (and we have concrete walls so I'm assuming it's part of the problem). Instead of getting those power point extenders, we decided to connect an old router to our main router's ethernet port instead. The reason being is that our house is old, ad so is the circuitry so when I had it one time, it didn't work. Now that we have the 2nd router upstairs set up, my small devices (phone, tablet) are having issues connecting and would always drop connection. I should say that our main router is a D-Link DIR 1960 while our 2nd is a Technicolour tg799vac. I want to deduce that it is because they might not be compatible with each other? We considered a D-link mesh extender but as we are all students, we could not afford it. Is there a way we can fix this problem without anyone having to sacrifice internet connection for it? I have searched everywhere to try and find a solution and tried restarting everything but nothing seems to work. Any help would be greatly appreciated.
