I have a Netgear wifi router connected to my cable mode. It is a WGR614v2 model, and I have updated it to the latest revision of the firmware. It supports both 802.11b and 802.11g.
I currently use it from just one PC (cable modem has to be downstairs, PC has to be upstairs, prefer not to have a wire between them) - which is upstairs (one storey up, typical 60s British terraced house) and "along" a room - so the router is one storey below and one room's width horizontally away from the PC.
I expected pretty good reception really, from a Netgear MA311 PCI card (supporting 11b only), given the relatively short range.
The signal strength fluctuates between 6-20%, but regularly cuts out (at random, not dependant on movement around the house, or any equipment turning on/off) - usually at least once an hour.
Would I be best buying an 802.11g USB wifi device and hanging it from a loose USB extension lead, or should I get a stronger aerial for the router downstairs?
I have read that 11g has a better range than 11b, presumably this can be extended to mean that inside 11b's coverage, 11g would be stronger?
Netgear's own aerial to go onto the router promises half-mile radius coverage - I don't believe or want that, but half-house would be good. It has lukewarm reviews at http://www.ebuyer.com/customer/products/index.html?product_uid=50573
so I'm not completely convinced it would work. If the answer is that the aerial is the best option, what kind of adaptor would I need to connect it to the WGR614 router? I've spoken to Netgear by phone, but they mumbled and said they don't sell such a thing!
