Weak signal on pci card
The signal strength for wireless devices depends on a number of factors including:
The distance from the wireless router / access point or gateway.
The objects in the path of the direct line of sight signal, i.e. types and thickness of walls, metal objects such as kitchen appliances etc.
The directional characteristics of the aerial on the router / access point.
The physical position of the router, i.e. is is low down or high up in the room - the best position would normally be at a height which gives the best / clearest footprint for the wireless signal.
Do you have other wireless devices - what is the signal strength like for those when positioned close to the device with the Ralink PCI card?
How many wireless provider devices do you have, i.e. do you just have the one wireless router / access point or have you extended your wireless network using a second router or access point to give greater coverage?
Are there other competing wireless networks close to your own network, if so, you may need to consider setting a different channel than the default channel 11 that many devices use.
Also try to keep your computer wireless devices away from other devices such as wireless telephones, wireless remote controls etc.
Note: the slot used to host the PCI wireless card is unlikely to make any difference as the physical location of the aerial is only minimally changed by a couple of centimetres. Try rotating the computer case so that the aerial is directly facing the wireless router (to remove the case as another cause of weakening the signal being received).
