So… running openSUSE 12.3 x64 on a Lenovo ThinkPad T530, dual boot with Win 7 Pro.
At home, I can connect via ethernet or WiFi to my LAN with no problems. If I go out and about to some place that has a wifi hotspot, again, no problems seeing or connecting to the access point - in Win 7 or Linux (any flavor).
The problems start when I’m trying to connect via the wifi hotspot on my iPhone 4 in openSUSE. No problems in Win7, or previously in Ubuntu (sorry), but in 12.3 / KDE most of the time I can’t even ‘see’ the hotspot and have to set it up as a ‘hidden’ network. Sometimes that works… and sometimes it’ll show ‘connected’ and say it has an IP address, but there is no functional connectivity.
I don’t think the problem is the iPhone, really. I can connect to it as a hotspot just fine in Win7, other linux distros, and even with my Kindle. If I connect the phone to the laptop using a USB cable, it then sees it as a wired connection and works okay. Can’t seem to connect to it via Bluetooth either, but thats a separate issue 
Any ideas as to why this is being such a PITA? Anyone else having more luck?
TIA,
Monte

When openSUSE cannot “see” the iPhone hotspot, what is the output of the
following command?
sudo /usr/sbin/iwlist scan
/code/
When you get an IP but have no connectivity, please post the output of the
following commands:
/sbin/route -n
/usr/sbin/iwconfig
/sbin/ifconfig
machin-shin:/home/monte # /usr/bin/iwlist scan

FWIW, right now the iPhone is showing two connections… probably one wifi and one via USB cable. The laptop (openSUSE) shows the same. I unplugged the cable to get just the wifi info above.
Thanks,
Monte
I have used my iPhone to serve as a hotspot in the past without issue, but I think if you have the USB cable connected simultaneously, you end up with a wired ethernet connection which will take precedence over the wireless connectivity (assuming NM is controlling your network interfaces).
The usb cable only gets used when I can’t connect via wifi…
I sometimes found that the iPhone SSID broadcast was a little laggy, but as soon as
/usr/sbin/iwlist wlan0 scan
was run, I would see the iPhone’s AP SSID present in the NM connections list, and could proceed with connecting.
Occasionally, I found that I’d have to turn the hotspot off and on to refresh it before trying to connect - a quirk of the iPhone, (or maybe the service provider I’m with).

My post clearly said “sudo /usr/sbin/iwlist scan”.

All this looks normal and indicates that the connection is fine. The only thing
we did not check is name resolution. Try the following:
ping -c5 172.20.10.1
ping -c5 8.8.8.8
ping -c5 www.samba.org
I had a similar issue today:
- home WiFi worked for days (fresh openSUSE Leap 42.1 install)
- hotel WiFi worked
- iPhone WiFi hotspot was visible but couldn’t connect (double-check password etc.)
At least in my case it turned out that the name was the issue. Once I renamed my iPhone (and thereby the name of the hotspot) from “Sven’s iPhone” to “TyrellCorp” it worked. So I have to assume that this was the issue.
