Seriously fluctuating connection with Belkin Router

[Chrisand]

Hi all.

My problem is that the wireless connection between my router and my pc (about 10m away) fluctuates hugely and sometimes looses connections (when trying to download stuff).

I am using a Belkin N1 Wireless Desktop Card on my PC and my router is a Belkin N1 Vision Part: F5D8632uk4A.

My PC is running Windows XP. My ISP in the UK is Be Unlimited.

I tried with a laptop next to the router and I get a constant connection download speed(speedtest.net) of around 15 mbps. On the other hand my PC connection varies from 0.1 mbps to 6 mbps (average of 2.5). I guess if it was constant at 2.5 mbps it would be fine but the fluctuations are driving me insane.

I tried with both the router and pc card antennae around 0.6m off the floor but a door is slightly in the way of LOS. As such, I placed both on the floor and there is LOS between the 2 devices. My Router is located just to the side of my bed on the floor.

What is strange is that even my laptop, which I moved next to my PC and which does not have a wireless desktop card anywhere as near as good as the Belkin N1 gets a constant connections speed of 6 mbps. I just cannot understand why my PC gets a slower and much more fluctuating connection.

I also detected the other wireless channels in my area and changed from channel 11 to 9. The closest wireless was detected as having a very poor connection. Most people are on channels 11, 6, 5, 2 or 1 so I though 9 would be fine.

Some signal/noise details:

SNR: 42
Signal+: -42
Noise-: -100
SNR+: 58
Signal: -58
Noise: -100

I do have a wireless phone next to my PC (and laptop now) and even tried turning this off but it did not fix anything.

Mine does this and did do this.. I simply replaced the PCI Card in Desktop and it was fine.

However, that said, I would speak to Be Tech Support, they may send you a new router / change the channel etc.

Thank you for the suggestions.

I think the first suggestion is great and the same one I came up with but the problem is that I bought the pci card recently and paid a hefty sum for it... I would hate to buy a new one, even if it was just to check if there is a difference. Hmmm, somehow I think I will end up doing it anyway.

FYI, my pci card is a Belkin F5D8001UK N1 300Mbps Wireless PCI Card and about 6 months old.

I have already talked to BE and they do not have any other suggestions other than changing the channel, which I have already done (11 to 9). I guess I could change the channel to distance it even more from 11 (4 for instance), which might help but since there really is nobody with a wireless router close enough to influence my connection I am doubtful. I will try nonetheless.

Any other suggestions welcome before I go out and buy a new pci card.
