Revisiting this topic as fixes in previous posts are not working.
Just updated my two computers to lastest available version. Computer one doesn’t support windows 11 so got latest windows 10 home version. Computer two got upgrade to windows 11. But after connection issues, reverted to windows 10, but still has connection issues.
Ipad connects and browsers work so the modem appears to be ok.
The updates/upgrade put Windows Defender back in working mode. (I think I had it disabled previously and just ran Webroot, but I’m not positive.) So had two firewalls and antivirus working.
Chrome, Firefox and Edge all have the same issue.
Made sure Defender allowed Chrome (couldn’t find firefox in the list). Webroot was in protect mode for Chrome and Firefox.) I think this mode allows traffic but monitors it closely. I didn’t test changing these to allow. But I did turn off Webroot and it still didn’t work so don’t think the protect/allow mode is relevant…….
Played with turning off webroot and turning on Defender. Did restart. I was able to access a few websites before it quit allowing access.
Windows internet diagnostics couldn’t find anything.
Error messages vary. ERR_NETWORK_CHANGED, ERR_TIMED_OUT, ERR_FAILED, are a few of the messages. Although, Your connection was interrupted (ERR_NETWORK_CHANGED) seems to be the most frequent.
Also just tried typing “192.168.0.1” in URL window. Nothing.
Any ideas on how to fix this?
