Windows 7: MTU Limit - Test and change your connection's MTU limit

Hi

Looking at my router, the MTU is set at 1500 but when I ran the command netsh interface ipv4 show subinterfaces, the results suggests that over the wireless connection, the MTU was 1300 (see attached screenshot). I then ran the ping google.com command and only received successful results at 1272 i.e. ping google.com -f -1 -1272.

Any suggestions? I've no real expertise in this area but came across the posts as I've been trying to understand why transfers to and from my ReadyNas have been so slow.

Thanks

What wireless device are you using? I think some are limited to 1300.

Thanks for getting back to me.

I have a Sky router (SR101) running to three Netgear WNDAP360 wireless access units (am connected using 2.4ghz band). I've had a look in the admin pages of the netgear wireless points and can't see any reference to setting MTU. If I can't change anything on these wireless points, is it worth setting the network to run at 1272 (i.e. 28 below the 1300 limit) or is this going to cause things to slow down even further?

then i entered "ping google.com -f -l 1462"
I got reply (see the attachment capture2.png )

then I add 28 "ping google.com -f -l 1490"
I got reply:Packet needs to be fragmented but DF set. (see the attachment capture3.png )

If you have any solution, please help me.

Thank you.
