I wonder if anyone can answer my problem. If I connect my laptop to my broadband router using the wired LAN connection, I get get download speeds of between 5 and 7mb. When connected wirelessly I only get download speeds of between 1 and 2mb. Anyone any idea why this should be? I'm using a Dell Vostro 1700 laptop running Windows XP service pack 3. The same issue is also present on a desktop PC also running XP SP3 and using an Edimax PCI adapter with an external antenna. I previously had a Belkin wireless router, but am now using a BT Home Hub - the problem existed on the Belkin router as well so it's not the hub that's at fault.
Any help would be greatfully received as it's driving me mad.

Changing the channel number in the router sometimes helps with connection and speed problems.
Change it by a factor of 6, e.g. if it’s currently 12 make it 6 or if it’s currently 1 make it 7.

I've tried different channels etc but it makes no difference at all.

This is a difficult area and I did say “sometimes helps”.
Assuming you haven‘t tried them, here are a few more straw-clutchers:
1. Move the router to find out if nearby electrical or radio activity or something metallic is causing interference.
2. Go to Device Manager and uninstall the wireless adapter. Restart the computer and Windows should reinstall it.
3. Delete the wireless connection and set it up again.
4. On the laptop, go to Device Manager > Network Adapters > double-click the wireless one > Power Management Tab and make sure the check box is cleared against ‘Allow the computer to turn off this device……’.

Thanks will try what you suggested. I've spoken to a couple of other folk about this and they seem to think that it is simply a limitation of the 54g wireless protocol. They suggested trying upgrading my wireless router to mimo n1 for improved speed. Of course I would also need to buy a PCMCIA N1 card for the laptop to take advantage of the N1 speed - do you think it is a limitation of the 54g protocol?

Although the router is rated at 54Mbps it will never run at that speed but it should be capable of an internet speed of 5 -7 Mbps.
Have you deleted the connection and set it up again?

Yes, forgot to say that I have deleted and re-set up th connection with no change. I even went onto the Dell support website to re-download the drivers for the 1390 WAN card but that made no difference either. I've since purchased a MIMO N1 router, but as the built in laptop card is only 54g there's obviously no speed difference. I'm going to buy a PCMCIA N1 card for the laptop and give that a try. I guess it probably is a limitation of the 54g set-up as the speed restriction is present on every PC I've tried on my network. Thanks for all your help though...

I wouldn't be so sure about the speed difference between 54g and N. The definition 54g actually means that it's capable of transferring data at 54MBS, far in excess of anything your network could throw at it. However that speed is moderated by the router itself sending checksum data packages to make sure that the data is being received correctly. The router will automatically reduce the speed until it is satisfied that the data is correct.
The wireless N standard has brought in a lot of upgrades to make the connection more reliable than 54g but it's still not intrinsically faster in data transfer because it doesn't need to be. If your broadband connection is only receiving data at 7mb it can't get any faster over a wireless network. The reliability of the signal and the greater distances over which N can transmit means that it may give you a better result but it may not.
In both 54g and N the position of the transmitter and receiver is far more important than a simple upgrade. The very best signal will always be if they are in a 'line of sight' configuration. The more walls, floors and doors in the way, the slower it will be.

Thanks for the info. The laptop I use sits approx 1.5 metres away from the router, it is just through and internal wall with an open door so it's very close indeed. The connection speed anywhere in the main living room is 54mbps - the signal does drop of I take the laptop through to the bedroom at the other end of the house, but it still only drops to about 24mbps.
The problem is though that the download speed on wirless only goes (at the most 3mb) so it's still a lot slower than on LAN. That is my issue. When on LAN I can get the full speed of around 7mbps.

A couple of factors to take into consideration is the amount of wiring and metal in the vicinity. Also any devices such as mobile phones or wireless telephones can interfere, as can any bluetooth enabled devices.
Try moving your aerial around or contemplate buying a wireless repeater
