Re: set up local wifi with NO access to internet

Advanced students? I'm sure that they can (will?) do that. Gotta remember that in public school systems (at least ours) The mode is to just make sure that you check ALL of the boxes. If that really doesn't do the job, then --well, that's for another day and someone else to add some boxes to check. T...

Re: set up local wifi with NO access to internet

Thx. My problem is that I have only superficial knowledge about networks in general. I tell my students to learn and really understand (at least) one level below where you are implementing. I'm really a 2-level-below guy, the first level solid, but at least anecdotal about he level below that. I giv...

Re: set up local wifi with NO access to internet

Update: I found an old Linksys WRT54GL v1.1 (2.4Ghz G) router in my closet. Just plugged it in and it generates a wifi signal named linksys. Selected that in my iMac and could easily run the GoPiGo3 with R4R. No internet connection -- which is what I want. Wonder how many users this could support? P...

Re: set up local wifi with NO access to internet

OK Thx. I'm running way past my headlights with this, and I won't get at it today, anyway.

Have a great Thanksgiving. My oldest son & family are hosting a nice dinner & get together. Very lucky.

Best,

Re: set up local wifi with NO access to internet

That's wonderful. I had no idea that the Pis could do all that. Can't wait to give it a shot. I really liked the way that the DexterOS had each GoPiGo3 generate it's own wifi signal. However my 40 min class wasted about 10 minutes getting the %^$#* Chromebooks to connect with the bot's wifi. Better ...

set up local wifi with NO access to internet

The school has a bunch of wifi networks. I have 25 GoPiGo3s (using Raspbian for Robots). Kids access them via a unique IP via VNC with their own computer (Chromebooks or PCs). The only thing that is important is to get each kid to access his GoPiGo3 (actually accessing the Rpi3B). No need for access...
