Why have to reboot, after using Starbucks wifi ~1hr?

Samwise Gamgee 2,574 229 October 21, 2012 at 09:21 PM
After using Starbucks wifi for about an hour, I have to reboot my laptop, then I can surf the internet again.

Is there a way to not have to reboot? Because my computer is really slow to finish logging in.

I tried ipconfig /release and /renew, but to no avail.

Is Starbucks blocking you in order to limit your WiFi usage? Have you tried simply disconnecting from their network and reconnecting?

Is this the case after you leave Starbucks and go home to your home internet? Or is it after being at Starbucks for less than an hour and you're still there when it goes out?

Yes. After about 1 hour, internet is cutoff (my wifi shows "limited" connection), until I reboot the laptop. I've also tried disabling and renabling the wifi.

Somehow their router (or whatever feature it's called) knows that I haven't rebooted. After reboot, I get an ip address, and the Starbucks wifi login page.

I just hate having to reboot my laptop, especially in middle of working, cause it take soo long to finish logging in.

This is the case, while I'm still there.

Did you ask management if there was a cut off limit? They may be doing this to prevent excess wireless sessions from just sitting there idle.

No. They'll probably just tell me there's cutoff. Just trying to see what I can do on my end, without having to reboot my laptop.

Try disabling the wireless adapter in Device Manager and enabling it again. The only thing I can think of is that the router needs to see the MAC address of the wireless NIC no longer connected in order for it to clear the session. That happens when a reboot occurs. Disabling the wireless radio just stops the signal from transmitting/receiving but doesn't disable the hardware. Try that next time.

There's no reason on starbuck's side you'd have to reboot. That would be an issue on your computer. If you turn off your computer's wifi and then turn it back on it's likely to work (turning it off and waiting a bit could be a good idea too), but you may have to re-authenticate with their captive portal.

Limited connection can mean several things:
-you aren't really connected, your computer's lying to you; usually driver issues or hardware issues
-you don't have an ip address
-you have an ip address but there's no route to the internet or you authenticate at a captive portal to access the internet.

run ipconfig and see if you have a valid ip address, 169.254* address means a problem on your computer. try to ping the default gateway and to tracert google.com

Also, sometimes captive portals can act up a little. When it cuts you off try going to starbucks.com or google.com you might get bounced back to the portal.

Cool, easy enough to try, thanks. I''ll update if it works.
Kind of like disconnecting the network cable from the NIC vs. disabling the NIC.

Earlier, I incorrectly said 'disabled', when I meant to say 'turn off' the wifi.
When I turn off the wifi, I use a physical button on my laptop.

Yeah, I wonder what they are checking, that still remains when I only turn off the wifi, but appears to clear when I reboot.

I'll try that too, thanks. I may be too impatient. Maybe the time it take to reboot, is the same time I need to wait, after I turn off the wifi, before turning it back on.

I'll have to take a closer look at the command line stuff next time.

I thought maybe ipconfig /release and /renew would trick it, but didn't. If I recall, the /renew part, returned "access denied".

Wow, thanks, this will be awesome to try ... the creating a new MAC part.

The spoofing someone else's MAC seems wrong, but perhaps fun to try. I may just have to try it someday.

On a side note, regarding MAC ... at work one day a computer just couldn't pick up an ip. Damn ... come to find out, there were 2 computers with the same MAC. That's when I realized, you have to keep in your knowledge, that MAC may not be unique.

Thanks All! Some good things to try. I will report back next time I'm at the Starbucks.
