Hi,

Just to add I am also having severe issues with a newly purchased 2925 for a fibre install.

Depending on the device I am seeing between 2% and 30% packet drops.

So far I have tested:

Laptop (Centrino N-2230 based chipset) - Between 2% to 5% packet drops.
Nexus 5 mobile phone - 30% packet drop. (it's incredibly bad on this that it is simply better to just use the mobile network..)
Nexus 7 (first gen) - 30% packet drop. (also incredibly bad on this)
Chromecast - BBC iPlayer test only so far but frequently stops to buffer and just gives up after a while (at a guess i'd say packet drops cause it to stop retrying)

The firmware is 3.7.4.2, does older firmware resolve this?

EDIT: For example...

Just to add to this I downgraded the firmware from 3.7.4.2 to 3.7.3.2.

I am now getting 0% packet loss on all devices, no issues whatsoever.

If others choose to do this then I recommend against using SSL VPN due to this issue which exists in 3.7.3.2.
