Download speeds on my desktop PC have been crap for the past few days. I have 100/100Mbps service from Frontier and I'm actually getting a little better than that on my laptop. I've checked my settings on the desktop and confirmed all my software and drivers are up to date. I also pulled the card, cleaned the contacts, made sure it was seated properly, etc. No joy.I have installed the recent Win 10 upgrade on both computers, but that was after things went wonky. For the past week DL speeds on my desktop have ranged between 5mbps and 30mbps. Uploads have been 3-5 times that, strangely enough. It's not consistent, either. One run will be 15mbps and a second on the same server taken right away will be significantly different. Time of day or night doesn't seem to matter. Tests run @ 1am are just as wonky as runs taken at 2pm. Both computers are on the same network. and the connections are wi-fi for both. My wi-fi router has 2.4GHZ and 5GHZ channels, as do the comps. Switching doesn't help. I'm guessing I need a new PCIE network card for my desktop, but figured I would post this in case anyone else has had a similar issue.
