Slow wi-fi speeds. Works fine wired.

Recently had Virgin Media 50Mb fibre optic broadband installed using the super hub 2. I'm getting fantastic speeds of 55Mb with a wired connection.

However, wireless speeds are only 16Mb. I have a full strength signal and have tried changing wireless channels etc to no avail.

Does anyone have any suggestions??

Thanks
 
Thanks for your prompt reply.

I previously had ADSL broadband and was only getting speeds of up to 8Mb/s. Hence the reason I went for fibre optic.

I currently have a TP Link WN851N wireless card installed. Features include:

IEEE 802.11n, IEEE 802.11g, IEEE 802.11b

So the laptop is only achieving 20Mbit because it only supports Wireless-G. It has no bearing on the slow wireless speeds you're seeing on the other PC.

What speed does the other PC manage with a wired connection? That's your only useful comparison.

You aren't running any nasty **** like Zone Alarm are you?

Is there an improvement if you boot the PC into Safe Mode?

The router is downstairs and I dont have a long enough ethernet cable to test the PC wired.

I've got AVG Free running on the PC.

My laptop shows around 10 wireless network (neighbours etc) whilst my PC shows only 2. The router transmits 2 wirelss signals (2G and 5G) but the PC only picks up the 2G one.

I'm thinking it might be a driver issue. If you look at my earlier screen shot, the adaptor shows as an Atheros AR922X.

The problem is that when I last remember trying to install the official TP Link driver, the PC would not pick up any networks at all.

Another problem I have is when I have the PC switched on for over 30mins and then try to run any installation or setup file, the monitor displays "no signal". I have to then switch off my PC and wait 15mins before switching it back on otherwise it will still display "no signal" if I don;t wait long enough. This has been going on for months unfortunately and I can't find a solution. I've tried re-installing Windows and even installing a new graphics card.

Anyway, I tried to again install an offical TP-Link driver but the monitor is showing "no signal". I'll try it again after waiting 15mins
 
That wireless adapter is based on an Atheros chipset so it's no surprise that it's using Atheros drivers. It's worth checking they're up to date, but it's nothing to be concerned about.

If I was you I'd fix the other problems and then worry about the wireless connection. You may find that the wireless fixes itself when the rest of the PC is working properly.

For a desktop PC I'd always prefer Powerline adapters to wireless (assuming running a cable was absolutely impossible).

OK, thanks for your advice and help.

I've managed to successfully install the official driver for the wireless adapter but it has made no difference in terms of speed.

Use inssider to see which wireless channel is least busy. Then change your router setting to this channel.

I'd just run network cables to each pc and only use wireless for mobile browsing
 
OK, so I've just purchased a TP-Link AV500 Nano Powerline Adapter Starter Kit.

I'm now getting 30Mb/s which is a useful improvement. However, I was hoping and expecting it to be higher.

My question is - will a more expensive adapter produce better results? Are there any highly recommended ones I could try?

Cheers
 
I was playing with a set of TP-Link TL-PA6010 AV600 adapters this afternoon.

The worst result I had was approx. 8MBps (64Mbps) That was between different circuits on different sides of a 17th Edition consumer unit (dual RCDs).

Upstairs to downstairs (but on the same circuit) I was seeing 20MBps (160Mbps). My old Devolo AV200 adapters only manage 7MBps using the same sockets.

I've never found my house to be very Powerline friendly. When I've used them at other locations I've had better results.
