WiFi as WAN with RT-AC68U

[DerBinski]

I have a RT-AC68U running 376.45. Now I bought a Huawei - E5786 - Mobile WiFi - LTE Hotspot http://consumer.huawei.com/en/mobile-broadband/mobile-wifi/tech-specs/e5786s-32a-en.htm. The device has no LAN port.

Is it possible to use the Huaweis WiFi as WAN in my RT-AC68U?

I use a openVPN tunnel for all my internet traffic when I´m connected with ADSL as WAN. (openVPN Client)

Will it be possible to use the openVPN tunnel when WiFi as WAN is used?

What are my possibilities? The setting Options in the E5786 are very simple. So perhaps I need some kind of "RT-AC68U as Client" mode. The Huawai has a 2,4 or 5GHz WiFi.

Perhaps it would be possible to use the 5GHz band as some kind of Bridge and the 2,4GHz WiFi for Clients?

Any help would be greatly appreciated .

Perhaps you could plug the E5786 into the router through the USB port. Then try Dual-WAN and USB 3G/4G mode.

I'm not sure that E5786 support IP over USB or detected as modem by RT-AC68U

yes


but all of these by your hand!!! and start-up scripts.

1. by brctl
- remove eth2 (5GHz) from bridge br0 (be daefault br0 conatain vlan1(vlan0) eth1 eth2)
- create new bridge br1 and add to it wan(vlan1 or vlan2) and eth2

2. connect eth2 to your Huawei by use wl and wlconf command.

Thank you for your suggestion but the AC68U will not detect the E5786 and it is not on list of supported devices. http://www.asus.com/event/networks_3G4G_support/

Thank you for your answer. I will try to build these startup scripts.

Perhaps you can go a little bit more in detail or point me to some howtos or threads where I can find more advise. I´m totaly new in scripting the router.

** JFFS ** and ** User scripts **

how-to use brctl : run in console with --help

how-to connect wifi interface to AP - use google

 

[DerBinski]

That´s what I managed t odo so far:

#!/bin/sh
PATH="/sbin:/usr/sbin:/bin:/usr/bin:${PATH}"

# services-start script

# remove eth2 (5GHz) from bridge br0 (be daefault br0 conatain vlan1(vlan0) eth1 eth2)
brctl delif br0 eth2

# create new bridge br1 and add to it wan(vlan1 or vlan2) and eth2
brctl addbr br1
brctl addif br1 eth2

But now I´m not sure with the WAN interface. eth0 seems to be the physikal WAN interface. But what is vlan1?

I don´t know how to add "WAN" to br1. Any help appreciated.

[AndreyPopov]

eth0 - is network 5port switch
eth1 - 2G wifi
eth2 - 5G wifi

try robocfg show to see what vlanX is WAN and what vlanY is LAN (vlan1 is LAN) then WAN is vlan0 or vlan2

IMHO: use init-start script

 

[DerBinski]

try robocfg show

IMHO: use init-start script

Thank you very mutch for your help again.

  61: vlan61: 5t

So I think WAN must be vlan2 right? If I get you right I have to add it to br1 now.

brctl addif br1 eth2

admin@RT-AC68U-EAE8:/tmp/home/root# brctl show
bridge name     bridge id               STP enabled     interfaces

                                                        eth1
br1             8000.bcee7bddeae8       no              eth2
                                                        vlan2

Is this correct?

I was not able to find good information on how to connect eth2 to the Huawei using wl and wlconf. Perhaps there are a few threads that I missed.

try this:

wl -a eth2 ap 0
wl -a eth2 join <ssid> key xxxxx amode wpapsk

 

[DerBinski]

wl -a eth2 join <ssid> key xxxxx amode wpapsk

will not work. Allways get the error wl: Unsupported

[AndreyPopov]

try use quoted ssid and key by "

[DerBinski]

try use quoted ssid and key by "

and set you Huawei WPA2-PSK AES (only)

There are three options in the Huawei 1. "WPA/WPA2-PSK" (set by default) 2."WPA2-PSK" and 3."WEP". AES option is missing. I used 2."WPA2-PSK"

 wl -a eth2 join "JARU-Net-LTE-Gateway" key "xxxxxxxx" imode ibss amode wpapsk

same result

 

[AndreyPopov]

also try wl -i

 

[DerBinski]

also try wl -i

thx

wl -i eth2 join "JARU-Net-LTE-Gateway" key "xxxxxx" imode ibss amode wpapsk

same here

 

[DerBinski]

I get stuck here. I´m not able to connect to the Huawei using the "wl" command in any variation. I searched in different forums but I can´t find code snippets to connect as a client to another WiFi.

When I Switch the router to "Repeater Mode" in the gui it will connect to Huawei without any problems.

Any hints, howtos or other options?


regards Binski

 

[AndreyPopov]

in repeater mode may used like this:
# connect to upstream AP
wpa_supplicant -D wext -i wlan0 -c /etc/wpa.conf -B

 

[SR-G]

Hey Binski.

I'm nearly in the same situations as you - Merlin firmware on an Asus router (RT-N66U on my side) with a huawei hotspot and, as my main wan provider (numericable / france) is really unreliable, i would like to wire the huawei hotspot in dual wan mode.

Did you managed in the meanwhile to achieve this configuration on your side ? Seems not so easy at first glance.

 

[IvanMelnyk]

Hi all, I have the same situation.
I have Asus ac68u with Merlin on board, open wifi network with online authentication (I mean through web-page, where you have to type login/pass).
What I expect is to have an internet connection through this open wifi network and share the internet to all of my users (on my local network).
So what I need is to connect to open wifi network with using one of my wifi adapters (2.4Ghz, eth1) and use it as WAN on Asus AC68U.
I was trying to do all the steps which is described here (with small modification):

1. remove eth1 (2.4Ghz adapter) from br0
   

   brctl delif br0 eth1

2. create new Bridge - br1
   

   brctl addbr br1

3. add eth1 and vlan2 (WAN) to new bridge br1
   

   brctl addif br1 eth1
   brctl addif br1 vlan2

4. change the mode of eth1 to wifi station
   

   wl -a eth1 ap 0

5. connect to open wifi network with using eth1
   

   wl -a eth1 join "WIfi-SSID" imode ibss amode open

And it seems connected to open wifi network:

But there is no internet, no login prompt on any of the client in my local network, neither ping nor traceroute works,
what I'm doing wrong and what needs to be changed in my config?
