My dsl router wireless shows no internet access on my laptop and on my iphone it takes time to go online. This happens with the 2.4ghz and the 5ghz networks.

The thing is when I'm connected to my wifi extender I have internent access and everything is smooth.

I tried resetting the router adn I contacted my ISP and still I cant seem to figure out where the problem is.

It used to work when I first got the router, but maybe something is wrong because Im constantly connected to the extender.
