tp-link ac1750 extender re450 no internet access
Trying to be as calm as possible I would like some help please.
Having gone through the setup with the tp-link ac1750 extender re450 I get no internet access on my phone or laptop no matter where I am in the house or if I use a wireless connection or ethernet cable.
The passwords I enter for the 2 bands (2.4 and 5) are the ones used on the router (sky er115). I have reset the tp link more times than I can count now (40+) with no change.
Having learnt about mac filtering there is none on the sky router from what I can see and the settings in the tether app look fine aswell.
All the lights turn on and I can connect devices to the tp-link but I never get internet access despite my router working fine as I have been using it on the other device to trouleshoot this issue.
Hopefully someone has an idea on what is going on and can help.
Note- I have split the bands and that didn't make a difference. I have run out of options.
