Hi again,
Sorry for the delay in my reply - I have been busy.
the connection is 10mb and the router doesnt actually have a model written on the box or the router itself, it just reads "net-lynx wireless broadband router" it then goes on to list the tech specs:
IEEE 802.11g / 54Mbps / 2.4GHz
Backward compatible with IEEE802.11b
Supports 64/128-bit WEP / WPA / WPA2 / IEEE 802.1x
Supports WDS mode
I'm not sure if there is firmware on the router currently, I did not receive a CD with the package so assume not. I considered flashing some firmware on myself but couldnt find a net-lynx router named as a supported router in any of the mainstream firmwares (DD-WRT, Tomato) so didnt want to risk it.
It is the router that disconnects and the disconnects only began when I fitted the router into the network.
I believe ventilation to be sufficiant, although it is kind of under my desk it is on the edge on a box on a platform and there is nothing near it.
Thanks for all your help and interest so far.
