Note, stopping the parallels access service or uninstalling parallels acces does not stop the internet dropouts. If I reboot the g3100, internet on the parallels access pc’s works briefly, then drops all internet traffic but local traffic between the pc’s is not affected. Any device that does not have parallels access installed has no issues at all whether it’s a pc, ipad, mobile device or any other network device. Local network between pc’s works fine 100 percent of the time even with no internet on those pc’s. I have 1gb plan and have Ethernet from ont to router for internet and coax to router for Fios tv boxes. After Verizon updated my firmware on the g3100 router to add another 5gz band on 8/20/21, any pc connected to the network with parallels access installed has constant internet dropouts. It resolved a big problem for me.I have had Fios for years with 0 issues. I've sent a link of this thread to Parallels and I will send it to Verizon's tech support. So one would have to assume that the trouble can be attributed to Verizon's hardware update. Parallels Access has been in use for a long time and my version was over 2 years old. The technician gave up trying to make it work and put in another. One interesting sign that the problem may not be just with Parallels Access is that when I put in the replacement G3100 then the device for my 2nd TV would not connect. Verizon tech support has been responsive, they sent me a new G3100 router and they sent out a technician to check the cabling.

I've probably got 40+ hours invested in finding out what happened. This has caused me quite a bit of trouble.

Fortunately I no longer have a need for Parallels Access so I can get by without it. I've not had any timeouts for over 24 hours, something that has not happened since early September. I uninstalled Parallels Access and rebooted.
