Upgrading Wireless Card


D@z©

Likes # 0

Hi I have a Dell Vostro 3700 which I believe has a built in 802.11g card. Can I upgrade it to a 802.11n which will get the most of my fibre optic BB? If so could you provide links on what would be a suitable purchase. Thanks.

Still looking for a replacement card - but an easier option for you would be to purchase a USB N adapter. otherwise there are instructions here on how to replace enter link description here

This is one a friend of mine purchased recently and had no problems enter link description here or if you want to pay a bit more I would go for the Edimax Dual Band enter link description here

Thanks, but if I am going to have ugly adapters etc I may as well go hardwired. I am really after a replacement card to go into the laptop.

Well they are really not ugly these days - some are tiny like this one (you can check the dimensions in the spec) enter link description here but I will keep looking if you want internal - or someone else may come up with a suggestion in the meantime.

I just bought this mini USB dongle for my Tower PC.

My laptop (2 and a half yr old Compaq) has built-in PCI Express Half Mini Card Wifi. See Items 8-12.

Easily accessible under panel on underside.

I haven't looked into it, but guess they are fairly standard.

To be clear, the OP should see what b/g card is fitted at present then replace with b/g/n card.

Bear in mind the router nay only be b/g but it's worth updating to 'n' bit by bit.

'n' standard freebie routers from ISPs surely won't be long in coming.

A further note:

My b/g router is close to a radiator at the far wall of the Living Room of a 1930s semi-Detached House.

Two brick walls through to the Dining Room, then brick to the Conservatory at the back.

I still get 'good' reception there, but wireless LAN speed is reduced to about 20Mbps.

ISP speed (see Speedtest.net) is not related to Wifi speed. My AOL, a mile and a half from exchange is only 4Mbps on an 8Mbps service.

I can't get better than that till the roads are dug up again.

Thanks for the input, I have looked into usb adapters etc but most only have a 150mbps transfer rate which is what I am getting now anyway. I think a couple of the cards look feasible that were pointed out on amazon. They have a 300mbps rate, so for a small outlay they may be worth a go.
