Our broadband speed is around 40mbps but for some reason my PC only gets 10mbps and my laptop gets 38mbps. My PC uses a usb wifi adaptor I have tried updating the drivers didn't work. I put the adaptor in my laptop and I got 32mbps so that works. I got a really long network cable and ran it through the house

I put the adaptor in my laptop and I got 32mbps so that works. I got a really long network cable and ran it through the house and plugged it into my PC and got 15mbps is something up with my PC everything else is getting decent amount of speeds. Probably should mention that the PC is upstairs but all the tests i did in my laptop were upstairs so that shouldn't change anything should it

Best Answer:

Luke Watson: First, lets get the speeds right. You mean Mbps (Megabits/second) not mbps (millibits/second). There are 10^9 mb in one Mb.

Ethernet connections are nearly always faster than WiFi, but both can be slow, if it is a computer problem, which from your question this sounds as though it is.

Assuming it is a Windows desktop you should use Task Manager and Resource Monitor to check just what programs and resources are being used in the computer. It may be that the CPU is being overloaded with other programs that you might not even realise are there.

As well as relying on a speed test program, you should also look at the network adapter status to see how many bytes are actually being transferred. Microsoft or anti-virus updates or even spyware could be loading up the network and reducing the bandwidth available for the speed test program itself.

Start by opening Task Manager, from where you can start Resource Monitor if you need it.

Good luck.

Other answer:

Luke Watson:
if you only got 15 Mbps on a network cable there must be something wrong with the pc.
David E:
Try putting USB adapter in a different USB port. There are some that don't run as fast as others. If you still have a USB 1.0 port, that will top out at 10 Mbps.

Your network adapter….your " nic "….most now a days are either 10 / 100 or 10 / 100 / 1000…..that means 10 meg / 100 meg / 1000 meg….now the adapter should have settings….auto ( it will do what it has to do ) or settings you can adjust……

Just for curiosity sake make sure your's is set to auto…

Palladini:
run a Ethernet wire from the modem to the computer, problem solved! If you want, at the end of The Ethernet wire, add a switch. Then from the switch, run wires to laptop. game machine, desktop, TV etc…….
comeback:
it depends on the distance on the MODEM and the WIFI RECIEVER and some factorsgoo
