I have not heard of wireless being a issue
but I can suggest, somethings that we find that helps run better, if you are using the GF client, look on the forums, its been posted how to run without the GF client which lags it alot,... run your game in Admin mode, some of my people have win10 and find running it in compatibility mode for win7 gives them more stability, there are several free softwares to help with the memleak (I use CleanMem) you might want to check about increasing your virtual memory in your computer settings, this was a HUGE help for us, we were crashing about 3 times a hour, increasing that, we are down to about once a day...
maybe someone will have a suggestion about your wired/wireless, but these are a few suggestions for just having a stabler rom ^.^ Good Luck!
