No data through hotspot

robster7674 commented 1 year ago

After activating the hotspot I can connect my laptop ok, but there is no data flowing. Are there additional steps I need to take? How can I troubleshoot?

Tested with beta27: still the same issue. After connecting my iPhone (iOS 15), I could not use internet on the iPhone, it just times out.

Here is a sample of nmcli with hotspot activated on beta27:

[manjaro@manjaro-arm ~]$ nmcli
wlan0: connected to Hotspot
        "wlan0"
        wifi (rtl8723cs), 02:BA:FD:F4:BA:94, hw, mtu 1500
        inet4 10.42.0.1/24
        route4 10.42.0.0/24 metric 600
        inet6 fe80::d315:7dc5:bf23:6e19/64
        route6 fe80::/64 metric 1024

cdc-wdm0: connected to Default
        "cdc-wdm0"
        gsm (qmi_wwan, option), hw, iface wwan0, mtu 1500
        ip6 default
        inet6 2a02:a420:4f:4f3b:e94f:5b5d:b668:fb35/64
        route6 2a02:a420:4f:4f3b::/64 metric 700
        route6 default via 2a02:a420:4f:4f3b:fc95:c848:b535:450b metric 700

p2p-dev-wlan0: disconnected
        "p2p-dev-wlan0"
        wifi-p2p, hw

lo: unmanaged
        "lo"
        loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536

DNS configuration:
        servers: 2a02:a47f:e000::53 2a02:a47f:e000::54
        interface: wwan0

Is it expected to have only ipv6 DNS servers in resolv.conf?

Connection from MacBook to PinePhone is fine, as I can ssh from it to the phone.

[manjaro@manjaro-arm ~]$ nmcli d
DEVICE         TYPE      STATE         CONNECTION 
wlan0          wifi      connected     Hotspot    
cdc-wdm0       gsm       connected     Default    
p2p-dev-wlan0  wifi-p2p  disconnected  --         
lo             loopback  unmanaged     --

How can I further troubleshoot? https://github.com/gartfr/QualcommLTE has some useful commands, but I do not have enough experience/knowledge with mobile connections to make good use of them.

I suspect there is some issue with my APN config or something like that, as it appears that for other people the hotspot works fine. I am using KPN as provided in The Netherlands. Using the same SIM card in iPhone allows enabling hotspot with no issues.

Discussing this on my provider's forum (https://forum.kpn.com/toestellen-en-besturingssystemen-126/pine-phone-linux-manjaro-phosh-als-hotspot-instellen-geeft-geen-internet-op-laptop-580507, Dutch) learns that my phone only gets an ipv6 address for its data connection. Therefore I looked into setting up NAT64 and that succeeded, but I still don't get data on my MacBook.

I followed https://wiki.archlinux.org/title/Internet_sharing#Enable_packet_forwarding to setup ip forwarding.

I added the ipv6 pool as mentioned on: https://www.jool.mx/en/pool6.html#nat64-jools-pool6
