Great signals, but bad Mbps?

[Rinor91]

Hey there. My english aint the best, but i will try to explain my problem.

I'm using a wireless adaper on my computer to get wireless connection. That adapter allows 150 Mbps, and is called AL25150. (Jensen Scandinavia)

The internett i'm using is also used by 3 other, wich makes it a total of 4. 1x with cabel and 3x of us with wireless.
We have a pretty good connection i think. 25 Mbps if i'm right is the connection supposed to be in the house. Wich is pretty good in our country. When i turn my wireless on , and i'm sharing it with 1 or 2 others, i MAYBE get 1 Mbps; even when my signals says 4/5.
If i'm alone home, i can get 5/6 Mbps, wich still sucks. BAD BAD throughput.

To figure this problem we bought a extanded thingy to make the internet even better, and now i have 5/5 signals, but the connection is not so much better. Actually pretty much the same.

The x2 other people using laptops (no adapter), and they dont have big of a problem. (they stay around 7-10 mbps)

Is the router problem, my adapter, or can it be something on the settings on the router? (At this point i dont have information on how settings are on the router, i'm not the one "controlling" it, but if this have a part of the solution, i can get it)

Some extra information:
*I have the latest driver installed for the adapter.
* I have tryed to change the channels, without any luck. (Will use 6, 9, or 11)
* I have WPA2 Personal security.
* The router is 10 meters away, and 2 walls between.
* The router is called: Thompson TCM 471
* Our router has vendor at Apple inc and the extander from Netgear. (Got this from inSSider)
*As we speak, i just did a test on speedtest. It was 1.15 MBPS (with all 3 of us using the wireless)


I would love some good answers Thanks!

1. Speed test only measures your speed to an external server. most ISP only guarentee your speed to the ISP.
2. What wireless band are you using G(11MBPS) or N(100MBPS)?
3.usb wireless adapters are terrible because the data has to move over the USB Bus at usb speed.

2. 802.11g and 802.11n on the extander or (2.4GHz if u ment this )
3. What do u propose?

First thing to try is to move your machine to where the other laptops work well and see what happens. You also can try a long USB cable and put the device remote from your machine. Many times the machine itself will block the signal for these tiny network adapters. Also if you are running a very old machine it may only have USB1 type ports. These have a maximum speed of 12m but many times run much slower. You really want to have usb2 ports to run network cards.

As you found out extenders many times just slow you down. They will at a minimum cut your speed in half. Signal strength is not as important as signal quality and a repeater will just introduce more errors. The key to signal quality is interference. It is trying to find the source of interference and eliminating it that is hard. Mostly the solution is to run on different channels and hope it is better but in your case not. If you have a dual band router you could try buy a adapter that runs on 5g. Generally there is less interference but the signal also does not go as far because the walls and air absorb more of it.

My computer have USB2 Moving my computer is trouble, but i did move the laptops to my room, and they had the same Mbps.
My router is called Airport Express. This can be very usefull to know?

BUMP

This other day i managed to get the mbps as it should be. It actually went up too 20 mbps + WITH others also having the same.

But after a while, it went littlebit down, then more, and more, and at the end it become 1.0 mbps.

The next day it looked fine, but again it went down.

Now the last 2 days, it have gone to the mbps as it used to be. (ALSO LOW when others are on), even when i'm alone it is not more than 7/8 MBPS.

Was it random that other day when it became good or what? The thing i did that day was to reset the router, put my adapter on another computer, and reput on my computer again. That worked fine. But i guess that was random good MBPS for some hours?

HEEEELP
