I've recently moved into a new flat, connected to new ISP (Orcon), and have set up the ISP-provided Dynalink RTA1320 modem paired with an old D-Link DI-524 wireless router that one of the flatties provided. This setup is generally working well for everyone with laptops in close proximity to the router, however I'm using a NetComm NP545 wireless usb adapter to hook up my desktop down the other end of the house (maybe 3 or 4 walls in between).
Now, half the time I can get a decent signal strength and speed (5.8Mb/0.8Mb). The rest of the time the signal drops out completely, or is very weak and I cannot connect using Windows Zero or the NetComm utility prog. Rebooting the router and/or the desktop sometimes helps, mostly does not.
I'm wondering whether this is more likely to be the fault of the wireless usb adapter or the router, or the combination of walls and distance affecting things? I often check the signal strength from the router on my iphone and it seems to go up and down in a similar fashion to that received by the desktop. There is a kitchen between the router and my desktop, but the problem occurs without the microwave in use.
Orcon is sending out their Homehub (a Siemens SX763 i believe?) so I can try it to see if there's an improvement, otherwise I'm also considering buying an internal wireless adapter card.
Any other thoughts as to what the issue could be?
