|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.
