I am using an Netgear WNDA3100v2 USB card and a Netgear WNDR3700 router using the latest firmware revision. The USB card is attached to two USB extension leads to maximise signal strength. Router and device are about 10 metres apart on the same floor of an apartment. Practically I can move the router around up to a metre or so. I do have non-N clients connected to the same network, but it is not possible to have them all operating on N.
My issue is that 802.11G network gives a signal strength of 74% and N at 34%. My N network syncs at 81Mbps and occasionally flicks up to 108Mbps. I have tried changing the N channel to every available option, and the N link speeds varying upwards from 13.5Mbps.
I would like to get the best possible performance out of this config as the network will largely be used for multi-room multimedia streaming.
I am wondering if there's any tweaks or suggestions someone can provide for this config? Possibly a firmware hack would be of use?
