connectivity problems?

[AgataSays]

I'm not sure if there has been a forum topic on this yet or not, but team 3553 has been having a connectivity problem with our cRIO, basically: we've been having sporadic connectivity problems with the cRIO both wirelessly and through ethernet.

The ways we've tried to download the code (Labview) have included using the crossover directly from the CM to the cRIO, as well as wirelessly through the settings directions given through the FIRST website.

Troubleshooting:
1. re-imaging the cRIO- same problems- but it was sporadically connecting when connecting with the crossover, that is sometimes it worked and sometimes it didn't - that is, we tried all combinations of resetting the cRIO, powering off, restarting the comp, etc..
2. resetting the dlink- could not configure to new settings- it froze whenever we tried to save settings when set to AP- and when set to Bridge it didn't show us the full menu.
3. changing computers- tried using a different PC to save the settings on the dlink, same problem- wouldn't save.
4. re-imaging the Classmate- after re-imaged, we had the same problems with not being able to communicate.

what else can we try? is it something with the dlink?
