I'm running a Pi 'B' and PiMAME software. I've got a Netgear USB wireless dongle that I'm using for networking. It's at a fixed IP of
However, the network randomly (it seems) just...goes away.
Example pinging it:
This is with it just sitting at the main PiMAME menu.
Any thoughts?
Many thanks.

The simplest thing to do might be to change the dongle. With the widespread use of WiFi, you also may have some sort of interference problem.
Apropos of nothing, the inexpensive USB/WiFi dongles on my win7 machines seem to be more reliable than the expensive ones. ????

Not thought as such, but I've got a PiB+ sitting on a network using an Edimax WiFi dongle, and that is not dissimilar to what I see. Sometimes I get really fast pings, other times it can be over a second, sometimes no response (which can last for hours) I've got a cron job that pings the router every minute, and logs the results (along with the CPU and GPU temperatures).
From Yesterday's log (times are milli seconds):
1040 - 5.618 CPU temp=41.7 C GPU temp=42.2'C 1041 - 3.649 CPU temp=41.7 C GPU temp=41.7'C 1042 - 1335.856 CPU temp=41.2 C GPU temp=41.2'C 1043 - 17.311 CPU temp=42.2 C GPU temp=42.2'C 1044 - 19.257 CPU temp=42.8 C GPU temp=42.8'C 1045 - 19.300 CPU temp=42.2 C GPU temp=42.2'C 1046 - 165.862 CPU temp=42.8 C GPU temp=42.8'C 1047 - 13.649 CPU temp=43.3 C GPU temp=43.3'C 1048 - 21.424 CPU temp=43.3 C GPU temp=43.3'C 1049 - 927.680 CPU temp=42.2 C GPU temp=42.8'C 1050 - 12.454 CPU temp=42.8 C GPU temp=42.8'CAdrian
Firewall behaviour?
Duplicate IP address somewhere?
Nope, no firewall in action and I'm very sure that it isn't a duplicate IP.
I'm wondering if, as was suggested elsewhere, it's a Netgear thing. The dongle performs flawlessly on my W7 box though.
Since I have a need for a second dongle anyway, I'll get a new one for the Pi.
Any recommendations?
Jim
I had some issues with older broadcomm chipsets, and Linux.
Issues that sound similar - sudden lack of comms, for a few seconds.
The US raspberry web site (Lady Ada, etc) mentions that there have been problems with various WiFi adapters. I've had better luck with the little cheap no name adapters than the common name brands.
The last really bad go around I had was an adapter that worked flawlessly in XP, sort of OK in early win 7, then more erratically with later 7 & 8. That adapter was a name brand "long range" adapter. The mfrs drivers were updated several times, each time improving things, but not quite fixing the problem. There was some sort of initialization/reset problem as far as we could tell. Sometimes just unplugging from one USB port and plugging into another worked. Disabling the driver, and re enabling it also sometimes worked.
