Sky Boradband Router issues

I've recently got Sky broadband Max, and get 10-12Mbps on a wired link
to it which is nice. But if I go wifi I get a maximum of 3.5Mbps. The
router and laptop are set to 802.11g mode, and full performance, not
battery saver.

I've asked on a router group and someone told me that it could be due to
the router not processing throughput fast enough.

So, is anyone else having the same problem, or are your routers
performing as expected?

Your PC uses different setups for each interface. It sounds like the MTU
used with the Lan interface direct to the router is OK, but the MTU for say
a USB Wifi dongle is not. You need to try tools such as drTCP to modify the
MTU for the USB wifi.

Thanks I'll give that a shot.

Incidentally, it's not a USB dongle, it's the internal wifi card but I
can see that the same reasoning will hold true. However, the same is
happening on both my laptops, and both laptops work fine when attached
to my Virgin wifi router.

My router is already configured in that way - almost. I had it set to
'b&g' mode so I changed it to Auto 108 just to see what would happen,
but it made no difference.

Don't restict yourself to that single page I listed; look around the
SkyUser site as there is lots of good info there, and if you still cannot
find what you what then ask there - they have a welath of info, knowledge,
and friendliness.

Check what speed tour wifi is using according to the info tab of your wifi
device. The 58 speed is a maximum for that device, it can easily down grade
down to 11. Even then wifi has a severe overhead, about 50% goes on
overhead. So if you have a downgraded link working at 11, it can't perform
better than 5.5, and once you include internet overheads a 5.5 link might
quite easily perform no better than 3.5.

P.S. If the wifi isn't connecting at the full 54g try another channel. My
125G connection is only reliable using channels 7 and 8, many of the others
can't even handle 54g!
