In the past few weeks I have been having issues with connecting to websites when on Cox wifi at home. Suddenly I can't connect to my online banking or other sites, just error messages. But if I switch off wireless and use the mobile network I can connect no problem. I believe this might be a DNS issue. I chatted with Cox and their solution was to split the network into 2.4 and 5g.
It made no difference. I have restarted router, tried using set DNS in my phones. No change.
Anyone else experienced this or have a solution?
