cannot ping roborio

[MikePerreman]

well, new development if i connect over ethernet, then connect over wifi, all is well, untill, i connect to a different wifi, then back to the bot, it wont re-connect to the bot.

When it fails to connect to the roboRIO, to see if it helps you might try:
cmd prompt> ipconfig /renew

Your PC may be retaining the previous DHCP address it was given.

[MikePerreman]

alright, if this works, is there a way to automatically do this every time i connect to a new network?

EDIT: i found out that task scheduler existed.

[MikePerreman]

Alright, it seems to be working now. ill update if anything goes wrong. Thanks for the help, Mr. McLeod!

[Mark McLeod]

Glad you got it working!

[MikePerreman]

nope, i spoke to soon, its not re-establishing comms after putting ipconfig /renew into run once i connect to the bot radio. however, if i reboot, then, before connecting to any other networks, it connects fine, but once i connect to the shop internet, it no longer works, even with ipconfig /renew

[MikePerreman]

also, im not sure if this is related, but i keep dropping connection to the shop wifi, when i do, i can connect to the bot, 9/10. this is starting to sketch me right the frig out.

Here's another series of commands to try (all as administrator):

• cmd prompt> netsh winsock reset
• cmd prompt> netsh int ip reset
• cmd prompt> ipconfig /release
• cmd prompt> ipconfig /renew (just listing this for completeness)
• cmd prompt> ipconfig /flushdns

You can try reinstalling or updating the PC's wireless driver through the Device Manager (Update Driver on the Driver tab for the wireless adapter) or if you can locate the latest network adapter driver software on the manufacturers website.

When the PC doesn't connect, you can try disabling, then re-enabling just the wireless adaptor.

See if you can find a local network expert to take a look at what your pc is doing. Without being able to put my hands on it I'm just going to be shooting in the dark at this point.
That doesn't mean I won't try.

We had a Windows 8.? computer at a quick build a couple of years ago with a similar issue. The operator selected Public from the list of network location choices (Home, Work or Public) this caused it to block the IP of the wireless connection on the router.

Depending on the Windows version, this can be difficult to diagnose and reset to allow it.

Search for "how to change network location to private" and follow instructions based on Windows version.

yes, the network is private, and there is no network professional available to us, we could do something like team veiwer, but i dont know.
