Hello, I have a problem with the operation of the wireless network with Vectra. I have purchased a 150Mb / 15Mb package and everything goes on the cable within these limits. The problem starts with the wireless network. I have a cisco epc3925 modem router. Console, stationary, laptop and 4 phones are connected via WiFi. And here it gets interesting, ie there are terrible fluctuations in speed. On all devices, the signal strength and link quality are 100%, i.e. there is no interference. But what I noticed is the fact that with the connected console and stationer everything works fine, speeds are about 80-90Mb / s, after connecting an additional laptop it can drop even to 2-4Mb. And now the question is, what could be causing such a thing?
