Topic: Problems connecting to WLAN

I recently got my chumby and in general I absolutely LOVE it. But there's one problem that drives me crazy, it has huge problems connecting to my WLAN.

So far I haven't seen any pattern. Connecting to my WLAN doesn't work at least 8 out of 10 times, it always shows:

wlan0 link is down
failed to obtain IP address
chumby.com is unreachable

But then, without anything being changed, it suddenly works. Sometimes right after I switch it on, but it usually takes 5-20 connection attempts. And once it works, the connection seems to be quite stable, as I have never seen the connection being lost once it was connected. If the connection is up, the link quality is about 80%, which I guess is not great but not critical either. I have a few other WLAN devices and I have never experienced any WLAN problems with any of them until now.
There is a setting on my WLAN router to automatically reduce the WLAN signal strength (for example signal strength is lowered if no WLAN device is connected) - I thought that might be problem, but switching the setting off and always sending at 100% signal strength didn't change a thing.

I don't know what else to try - does anyone else have an idea what the problem might be?

Re: Problems connecting to WLAN

I would try attaching your chumby to another network to see if the problem persists, if it does, the issue may be with the chumby.  If not, then the issue may be with your router or something else environmental.

Re: Problems connecting to WLAN

Thank you very much for trying to help, that really sounds like a good idea!

I actually already tried connecting to another WLAN. I took my chumby over to a friend of mine to show it to him. I had the same problems connecting to his WLAN, but after the third unsuccessful connection attempt I gave up and decided to show it to him another time, so I can't really tell if it was really exactly the same problem. Theoretically I could have entered the wrong encryption key or something, though I don't believe that.

But I will look into this more deeply when I'm going to visit another friend of mine later today.

Re: Problems connecting to WLAN

I just tried to connect my chumby to another WLAN. It didn't work.
After about three connection attempts the "Connecting to network" screen suddenly stayed much longer than before (about two minutes I guess), and afterwards the message "wlan0 interface is down" was shown (in addition to the usual "wlan0 link is down / failed to obtain IP address / chumby.com is unreachable" error message). I can't remember having seen that error before.
I tried a few more times without success before I gave up. Signal strength definitely wasn't the problem as I placed the chumby directly next to the WLAN access point. I also double-checked the encryption key, made sure there is no MAC filter enabled etc.
I even reinstalled the firmware and factory reset the chumby to see if that changes anything, but it didn't.

Since I have now tried three different WLANs with three different WLAN access points, I'm starting to wonder if my chumby has some kind of hardware problem. What do you think?

Re: Problems connecting to WLAN

We have two Chumby One units that are doing the same exact thing.

After a reboot 90% of the time these units will come up with wlan0 is unavailable. We did some digging into the dmesg output (as compared to dmesg on a good unit) and it appears that the wifi radio is not working.

On a good working system you will see 8021 message around the 15sec mark and wlan0 messages around the 30sec mark. On a bad system you don't see any of these messages.

It would appear that this is defective hardware. Is this a known issue? Should we send these units back to be replaced?

Re: Problems connecting to WLAN

FYI:
My Chumby retailer told me to return my chumby to get it replaced.
I did so and got my replacement chumby today. Unfortunately the replacement chumby has exactly the same problem, so I suppose that my first chumby wasn't simply a defective unit and it's a common problem all chumbys would have.
It's a bit annoying, but since the connection seems to be stable once it is up, I guess I can live with it.

My replacement chumby doesn't have a defective pixel like my first one, so in a way I still benefitted from replacing it.

My retailer told me that it's common that the chumby has problems connecting to WLANs, especially if there are many other WLANs in reach. Since this is indeed the case where I live, I guess the problem might have to do with the other WLANs. On the other hand, that doesn't explain why my chumby had problems connecting to my friend's WLAN, because he doesn't have many other WLANs in reach.

Maybe I'll try switching the radio channel that my WLAN access point is using, if it's really the other WLANs causing that problem that might eventually help.

Re: Problems connecting to WLAN

I had troubles connecting to my WLAN with a couple of Chumbies and found that things improved when I set them to have a static IP address each.
My connection problem was a little different to yours, from what I remember, I don't think I used to get the 'wlan0 link is down' message. However, it won't hurt to give it a try.
