Need help configuring Android USB tether on hAP ac2

RouterOS Beginner Basics
1

Hi all,

I just bought the new hAP ac2 with RouterOS 6.41.2.
From the default configuration, I did the following to configure for Android tethering:

  1. Attach the phone via USB port and turn on USB tethering
  2. Interface lte1 automatically detect on the interface list.
  3. Add DHCP client on lte1 and add default route. Check that the interface is bound and IP address received from Android phone.
  4. Add new firewall rule (srcnat , action = masquerade , out interface = lte1)

but clients connected to wlan and lan ports are not able to access internet.

Is there anything else to do?
Is the default config of eth1 as WAN has anything to do with this issue?

Thank you.

Is it possible to ping some domain or address via ROS console?

Please add ether1 configuration, such as dhcp client and ip address. Also show routing table.

Thanks

[update]

I don’t know why but after factory resetting the router and start again from scratch, it works now, sort of.

New problem is that the LTE connection speed is super slow (virtually unusable) compared to tethering the Android phone to my PC directly.

  • Direct tether to PC = I can speedtest for around 20/5 Mbps.
  • Tether to MikroTik I can’t even able to finish speedtest and request time out almost all the time in web browser.

I am aware about the double NAT going on here (Android USB tether NAT <192.168.42.0/24>+ MikroTik NAT <192.168.88.0/24> to the PC) but not expect it to be this slow and unusable.
Is there anything else I could change to make it better?

Thank you.

I have configured Mikrotik for Android tethering several times. Everything was ok.

After you activate tethering on the phone, does router get an IP address?

Is it possible to ping from router?

well i think, i had similar problem.

i have a ftp server in my android phone, plus i use this phone as my secondary internet connection, connected with my RB951G using usb tethering. this works perfectly on ROS 6.35.2 stable.

however, the problem began when i chose to upgrade to 6.43.16 longterm. very strange i could connect to ftp server, transfer files without any problems. but i couldnt connect to internet.

then i tried to downgrade the os to 6.37.5, because accidently my RB got stuck and failed when i was downgrading from 6.43.16 to 6.35.2. so i chose 6.37.5 it is nearest available netinstall, bcz others was 404.

the 6.37.5 has this problem too, i could connect to ftp server, but i couldnt connect to internet.

then after downgrading to 6.35.2, everything works again :smiley:

this is my little story, sorry for my bad english
