I intend installing a PCI wifi card in my XP tower. The antenna is the usual short stub and would be quite near the floor behind the PC.

For various reasons the wireless router must be located in an adjacent room at about head height and almost in line with the front of the PC.

This means that the XP case would be in the straight line signal path to the router. As the PC is a "grounded object", can anyone say from experience whether it would severely attenuate the signal?

Things that can interfere with wireless signal strength:

- Excessive amounts of interference from other wireless signals on the same wavelength
- Excessive amounts of concrete between source and receiving unit
- Excessive amounts of metal between source and receiving unit.

If this is a typical drywall wall, your signal strength should be very good and you have nothing to worry about. Before you go worrying too much, hook everything up and see what happens.

Thx Curt

Yep, agreed, wall should be fine.

My main concern was the possibility of the tower case screening the signal.
I haven't bought the card yet and I was trying to get some idea whether I would have a fair chance of success.

Just to say, I purchased the PCI Wifi Card (TP-LINK TL-WN651G) and the signal is generally low and unreliable. They claim 100 Meters yet my router is only about 5 Meters away (in line of sight of the tower front if the wall wasn't there).

I feel pretty sure it is what I first feared, that the antenna near the floor behind the tower is the main reason. The signal therefore has to go through the tower to reach the router. The wall is only single skin breeze block internal.

Undaunted I have ordered an antenna extension cable and will try raising the antenna up from behind the tower.

I'll let you know what happens.

Thx

Well, I was proved wrong. It was "the wall" that was the main trouble, which seems surprising because it is just an internal breeze block wall. Maybe there is some metal in it - who knows.

Anyhow, by carefully positioning the antenna at then end of the 3M cable (quite near to the wall), the results are very good. The exact position was quite critical within a few inches but the signal has remained steady in the chosen postion.
