Firefox stops working several times a day & cannot access websites. PC is connected via Ethernet to the modem/router. I get a message website cannot be found. I called the ISP a couple times & they show me connected to the internet.
Firefox will not completely close & let me run it again. Task Manager lets me remove all but one occurrence of FF, which prevents me from running another copy of it.
I end up restarting the PC several times a day to get connected again.
The last time I was looking in Control Panel > Network Connections & that window froze & could not close out of it. I could open FF over the Control Panel window but could not run FF. I let it sit while using a wireless device to look up stuff. The monitor went to sleep because there was no signal, probably because the PC went to sleep. I could not wake up the PC & had to power it off.
Another time Network Connections > Local Area Connections was stuck on "identifying..." and never found the router.
All this started happening after I tried a USB wireless adapter & installed its driver & Cisco software that got installed with the driver. I have uninstalled all this & updated the wired network adapter driver.
I tried to restore Windows back to an earlier date a couple times but a message said the restore was not successful.
Any suggestions would be appreciated, Thanks
