TP Link RE220. Certain devices wont connect but others will
Hi all got a strange problem and its honestly doing my head in. Ive bought a TP Link re220 just to boost the signal upstairs. Works fine and devices can connect to it. However a certain device will not connect to the extender however it will connect to the router just fine, will also connect to other routers and hotspots in different locations. Ive found a work around and im wondering if someone may know the solution to what may be happening
Logged into the TP link and the default gateway,primary DNS and secondary DNS were not set to my default gateway however when i changed this to the correct gateway it works as it should do? ill be honest ive fixed this completly by accident as im ok with networking just not brilliant. However if i change DCHP back from "on" to "Auto" it doesnt work again.
Unsure if im missing something, confused why I have to change certain settings when it works fine with other devices
