Not tried it yet but can i use this to make my Tower PC wireless? Or do i need somthing else?

Only reason I ask is i have this dongle for when i'm ment to be working

Unless it supports IEEE 802.11a/b/g/n you won't be able to connect to a wireless network. However, you will be able to connect to the internet via GSM EDGE or HSDPA (provided you've credit).

Far as i know it's a HSDPA, runs 3g on a 3.6thing.

Can i not use this to connect to the router?

Unlikely, but if you post the model number I'll have a look to see if it supports IEEE 802.11 (aka wireless and wifi).

Found out that it doesn't work, looks like hand in pocket time lol.

Thanks for the reply tho.

The O2 Mobile Dongles CAN be used to connect to a Home or Work Wireless Network.

I used one quite recently when a built in wireless card failed on a pc i was repairing

I'll give it a whirl now.

Bit of advice, if you have a spare PCI slot in your tower, get a wireless card not a wireless dongle. There are much fewer problems with cards and much better range. The cards come quite cheap, bought mine on ebay for £8 secondhand ages ago.

The same sort of thing with laptops, use a PCMCIA device rather than a wireless dongle.

I have ignored this advice to my cost in the past, once you get up to WPA or better still WPA2 encryption, there can be problems with dongles.

i second that.

although, if you can lay cat5e i would recommend that over wireless, anyday.
