Wifi access problem

IBM T42p
Win XP (Prof)
Mozilla Firefox

Live in a 2-storey house, with home network station (DSL service) located downstairs. Recently the previous Wireless G router was upgraded to Wireless N.

Now unable to access from upstairs with the laptop. No connection or very weak connection.

The laptop has: 11a/b/g Wireless Lan Mini PCI adapter
Intel ® Pro/1000 MT Mobile Connection

Bought and installed a Tenda Mini 11N Wireless USB adapter. Didn't do any good.

My knowledge is limited. Do I need to replace wireless card in the laptop or try another (more advanced model) adapter?

Kindly assist.

 

A few suggestions.

1. Make sure your new router is as high as you can get it.
2. Try placing the router in different areas and see if your signal improves.
3. If your router has a visible antenna then try orientating it at different angles to see if your signal improves.
4. If your router has a removable antenna then you might want to consider getting a high Db antenna.

Had tried suggestions (1) and (2) without success.

The router has no visible antenna.

Again, thanks.

 

OK, then try this for your laptop.

If you're in the US.

 

Shall try the TP-Link TL-WN722N 150Mbps High Gain Wireless USB Adapter and report back.

A recommendation a few weeks ago by PrivatePile. I have not tested it much, I went with the sure connection of a powerline device. I do agree that changing to N has not given most people more range.

From PrivatePile:
1) On the new router, are you broadcasting 2.4ghz or 5 ghz? 5 ghz may be the new technology and you'll think your getting the better technology, but a HUGE limitation to 5ghz band is that it does not carry well. It is highly restricted by walls and distances. 2.4ghz carries much better. If your using 5, try going with 2.4ghz and see if your signal is any better.


This would be a setting in the wireless router letting you change the band you transmit on.

 

Update

Bought and installed TP-LINK WN722N USB adapter. No improvement. Still shows
"no connection or very poor connection". Unable access Internet.

 

Using 2.4 ghz.

As stated in my previous message, the TP-WL722N USB adapter didn't work.

 

I'm guessing you are getting a good signal to the laptop when you have it downstairs. How far is the router from the stairs? Is it just in one area upstairs that you get the weak signal or is it everywhere? If the router is located very far from the stairs and you get a good signal at the top of the stairs you may want to consider a wifi extender like this one.

Thank you.

Shall give the Sabrent repeater a try.

FYI, the laptop receives strong signal when I'm downstairs.

The approx distance from the location of the router to the room upstairs is 60 ft.

Moving it to the stairs does not show any improvement.
