Can I connect laptop Wifi b/g with 802.11 n adapter

[SATAHDD]

I have 2008 model laptop 802.11 b/g wireless LAN and although my laptop detects wifi networks I am unable to connect to them thats because they are b/g/n? but there are backward compatible right. I was suggested to use a adapter/dongle will that solve my problem.

I have a link to the adapter below and my laptop model as well will it work or could anyone direct me to one that works.

My Wireless-G laptop still works with my 2.4 GHz Wireless-N network.

However, your computer may not work with 5 GHz Wireless-N networks.

Adapter should work, but generally those things don't have amazing range.

How do I know whether the wireless is 2.4 or 5 GHz?

and that's okay if I don't get an amazing range, I need to access Internet over my laptop at work place could you suggest a adapter that would work.

theses were the specification for an adapter

CF-WU810N V2.0 - 2.4GHz 802.11b/g/n 150Mbps USB 2.0 Wireless Wi-Fi Network Adapter
Its Support : Windows 2000/XP/Vista/WIN 7/ WIN 8 / WIN 8.1 / Mac OS / Linux
150Mpbs speed, Wifi Adapter, Soft AP, AP + Client
Realtek RTL8188EUS 150Mbps Mini USB wireless network adapter
Range: Indoors: 50-100 feet (Theoretical Value) Outdoors: 100-200 feet ( Theoretical Value
Virtual hotspot on Windows 8 via third party software. Phone supoort not available for Linux / Mac

If I use this adapter I would get up to 11 Mbps right not 150Mbps?

Some routers show 2 networks - one for 2.4 GHz, and the other for 5 (which you probably wouldn't be able to see).

That adapter should connect at N speeds - 150 MBps (though you will probably see less - it seems 78-104 are pretty standard speeds around my house, away from the router. It will ignore the WiFi card in the computer (turn it off if you can).

Yes I can see networks in both Win 7 and Ubuntu but they connect only when I plug in the Ethernet cable, not through wifi. What does that mean, sth to do with my drivers or any other configuration I need to setup manually?

Do you have a phone or anything else that connects with your workplace's network ok? It sounds like a configuration issue more than the computer's WiFi card itself.

Sometimes the network administrator must allow the computer into the network, or you have to do some sort of login to the network before it will stay connected.

Don't think it has anything to do with UAC.

It's either on the network's side (MAC address) to allow certain devices on to the network - my workplace does this - or you'll need to connect to the network and then go to a login page within your web browser and put in credentials.

This is just a guess, anyway. If you can see the networks, it *SHOULD* be able to connect.

Exactly I need to connect to the network in wifi and then open IP address in the browser to enter credentials (id/password) Internet only connects with ether net cable plugged in. I should play with the properties may be.

when the first time I tried to connect no network were showed later I logged in to ubuntu then I started to see networks in both Win7 and ubuntu but with out ether net cable it says net key not correct sth like that.
