Update: TCP Window Scaling / Receive Window / RWIN fix in post #29.
Firstly, this is a great site - lots of great info and resources.
I've got a 16GB Touchpad, and I've always thought that WebOS on a tablet would be awesome. Nuances aside, I still stand by that belief.
However I'm pulling my hair out over the following. I've got two wifi networks at home; one is running WEP (for "guest" access on a DMZ), the other WPA2 with AES encryption. Over the years we've had 4-5 laptops and 3-4 smartphones use one or the other of these wifi networks with no problem. My Touchpad also works well on either network...when accessing intranet resources (ie, streaming video over DLNA, using web applications on the intranet web server, etc).
But it's hit or miss (mostly miss) accessing anything on the Internet. This includes websites and updating feeds in preware.
The same thing happens when I set up a wifi hotspot on my Android smartphone: slow/no performance with the Touchpad, lightning fast on my netbook and my wife's laptop.
And yet... at work, the Touchpad is rock-solid accessing the Internet over wifi and ADSL.
This sounds like an MTU problem, so I've tried changing eth0 to use an MTU of 1400, then 1300. No difference. I think I even tried setting up a policy on my home Cisco router to clear the DF bit (Do-not-Fragment) and that didn't help either. And I'm pretty sure I've told the router to adjust the TCP MSS, and again no change.
Not to mention that none of these changes will alleviate the problem when using the smartphone's wifi hotspot.
So I'm stumped. Any suggestions from somebody with more Touchpad experience?
