wifi hotspot no route to Internet - dieselnutjob - 08-31-2021
Hi
I am installed arch/phosh yesterday
I got wifi hotspot working, and from my laptop I can ping the phone, but I can't get to the Internet.
I checked the ip forwarding is enabled, and it appears to be.
Can anyone help please?
thanks

Before we get to networking configuration, it's been noted in other threads that some mobile providers disable tethering by default, and you have to ask them to enable it.
What exactly did you do to enable a hotspot? I'd be looking at route and gateway settings, and whether you need to set up NAT.

I have used this SIM card in a couple of 4G routers and also in an Android phone using the Android "hotspot" feature and it worked fine.

1. settings -> wifi -> selected wifi network in use and selected "forget"
Now the phone has no wifi
2. turn off phone
3. insert SIM card
4. turn on phone
5. settings -> mobile -> Mobile Date slider to "on"
6. settings -> mobile -> Access Point Names -> + and set up the APN
7. terminal -> ping google.com then ctrl-c
8. settings -> wifi
wifi slider set to "on"
tap three dots
Turn On Wi-Fi Hotspot
Fill in network name and Password
Tap "Turn on"
Now another device can connect to the hotspot, and it cannot connect to the Internet.

I don't have a data-enabled SIM in it at the moment so I can't try it, but recent reports are that that method should work, at least in Mobian.

I'd guess that Arch should also work similarly. I don't know what that does with IPv6 though, which may be an issue with some mobile network providers. Have you installed a firewall that may be blocking things?

This bug/missing feature perhaps, or a similar corner case that's not handled yet?

I'm not really up to giving a step by step introduction to network troubleshooting in a situation with as many moving parts as this.

Same here, though DNS queries do work. This seems to be the relevant commands:

I do not use your step 1. or step 7.
For step 8. I do Not turn on wifi... just tap the three dots to open hot spot window > add name & password > turn on
(Elsewhere on this forum they do mention the wifi must be turned off before activating the hot spot.)
RE: wifi hotspot no route to Internet - antisol - 04-02-2023
Hi I found that after turning on wifi hotspot (which required having wifi turned on) I needed to enable routing through the phone's. Here's the script I use for this, must be invoked with sudo:
Code:
#!/bin/bash
if [ "`whoami`" != root ]; then
echo "You are not root"
exit 1
fi
iptables -I INPUT 1 -s 10.42.0.0/24 -j ACCEPT
iptables -I OUTPUT 1 -s 10.42.0.0/24 -j ACCEPT
iptables -A POSTROUTING -t nat -j MASQUERADE -s 10.42.0.0/24If I don't run this on the pinephone I get DNS on clients but no internet.
