I was hoping one of the IT-genius dopers could helps with something that has me stumped.
In the house, we have several laptops, tablets, etc. All are running at 25-30 Mbps, as they should because that’s what we pay for (30). Except one, that is consistently at about 4Mbps. What on earth would cause that? It’s a Toshiba 2-in-1 running Windows 10. Other devices range from an Ubuntu laptop to a Surface to ipad…
The machine is running McAfee, and as far as I can tell has no infections…
If it has an ethernet port, plug it directly into the router and see If the speed is still slow. If it’s faster when using a wired connection then the problem is probably with your wireless card. A lot of newer laptops, even better equipped laptops have crappie wireless cards.
You will also occasionally see certain combinations of routers/wireless cards/security that do not play nice.
As an experiment, go into your router and disable wireless encryption/security (its no big deal for a little while to test.)
Connect with no security…if its fast, its not liking your current wireless encryption. Most routers support 3-5 different kinds, try redoing security with WEP, or WPA instead of WPA2 and repeat.
If you change to another wireless encryption type you will rneed to reconnect all your wireless devices, but if that one is that important to you running a lighter form of security is rarely a crisis to your average home user.
