New Gig1 Install - Getting the same speeds as M500

[tintin_UK]

Per the title, upgraded to Gig1 from M500 yesterday but only swapped round the Superhubs early this morning.

On several devices standing next to the SH4, am only getting circa 500 in speed. Running the built-in diagnostic it suggested a problem with wifi but didn't say what exactly. I also received an automated proactive call from Virgin acknowledging that we might have issues and to turn the SH off for half hour which I did. No improvement. Stats below if that helps anyone:

Hub stats look perfect!!

What speed are you getting with a cat6 ethernet cable to a Gb enabled lan port of a laptop?

[tintin_UK]

940 down/50 up - which is good obviously. But doesn't explain the (comparatively) lousy wifi speeds in the same room.

Is this just the nature of the SH4? I only previously used the SH3 in modem mode coupled with an Airport Extreme but I think that's too old/slow to pass on the Gig1 speeds.

[lotharmat]

Are the capabilities of the WiFi card in the device definitely able to process Gb speeds?

A lot aren't!
