Has anyone noticed that the wifi connection is not exactly on much of the time? I currently cannot access my memory card via USB for some reason, so I installed ssh on the 770 and use winscp to transfer files to the 770 from my computer. Previously I could connect using winscp and use it for as long as I liked. Now to get it to connect I have to use the 770 on the network. Eg., load a web page to get it to read a directory on winscp. I am guessing this has to do with some power saving? I remember someone writing that to fix a similar problem they streamed radio. That is not the solution I am looking for. Any ideas? Should I put in a request for a switch to have the wifi connect constant? If so - where do I make such a request? Thanks in advance...

So - after trying several attempts at using scp on my PC (I used cygwin to get sshd running on my PC) and the 770 and having them all crap out at various points in the transfer (damn no resume in scp!) I decided to uninstall OpenSSH and installed Dropbear. The 360MB file I was trying to tranfer - transferred. I am not 100% sure that this cured the problem - pehaps I just got lucky. If I don't add to this you'll know... Thanks for listening.

EDIT: I think I got lucky. Winscp still craps out when I try to connect to the 770. hmmm...

I have had this symptom since day one, even with the 2005 OS and Dropbear. There must be an old thread lying around where I explained how pinging the 770 from a Linux box exactly every 4 seconds kept the link alive enough that I could ssh and scp.
Seems not all machines are quite alike in this though. Strange.
Haven't taken the time to try, but I guess the bast way to solve this is to use networking over USB as described in a Maemo Wiki Howto...

I haven't seen any connectivity issues. I use OpenSSH and I scp large files with no problems. (I do run linux on the PC, though)
Maybe it's your router or access point dropping the connection. I use a Linksys WRTSL54GS running a third-party firmware ( v2.00.5, HyperWRT + thibor15b ) I highly reccommend this router and firmware to anyone looking to buy one.

This never happened to me with IT2005 and dropbear but happens now with 2006 too. Maybe some keepalive ssh otion should help? BTW instead of USB you can also workaround it with bluetooth PAN if you have bluetooth in your PC. Works for me.
