There are 2022 and 951 series routers in operation and there has never been such a problem. I also recently purchased a 4011 router with wifi support for work, tested it for a week on 3 PCs and did not notice any problems with the device, according to the logs everything is normal, then we connected 7 PCs to it and in the logs I began to notice messages about interfaces on / off. Wifi works well, coverage is good.
