Dongle LTE limited to 7 Mpbs, Help

[Speedy1205]

Thank you for your posts Speedy1205! I tested shibby Tomato as you suggested.
I was able to get better download speed (20-30 Mbps) but for some reason i got poor upload speed (<7Mbps).

I like Asuswrt-Merlin and went back to the latest build. Then I remembered, that I have a Raspberry Pi B+ box hanging around, so I configured the Rasberry Pi as a router for my Huawei E3276 LTE/4G dongle and connected Asus RT-AC68U (wan port) to Raspberry Pi B+ (ethernet).

Now download and upload are ok.

I'm still in the "testing phase" so I'll let you know how I end up with the dongle and firmware.

hmmm this is strange.... I got the full speed my provider gives me:

Download: 20.39Mb/s
Upload: 19.63Mb/s

And this are rush hour times Normally Im by 30 / 30 .... So it is strange to see that this is not that good for you. I also would really stay with RMerlin Builds, but I just need a fast internet at home. Without this I can not work :-( Maybe at some stange it will be fixed or I will research it again when my R7500 is ready for OpenWrt so I can use it temporary as Gateway.

Hi,
I have tried to connect e3276 Hilink dongle to my RT-N66u as Speedy1205 proposed

admin@RT-N66U-8890:/tmp/home/root# ifconfig eth3 up
admin@RT-N66U-8890:/tmp/home/root# udhcpc -i eth3 -p /var/run/udhcpc1.pid -s /tmp/udhcpc &
udhcpc (v1.20.2) started
admin@RT-N66U-8890:/tmp/home/root# Sending discover...
Sending discover...
Sending select for 192.168.8.100...
Lease of 192.168.8.100 obtained, lease time 86400

But nevertheless I can not see obtained IP address 192.168.8.100 at ifconfig eth3 command and cannot access my dongle

Dongle is connected through powered (2A) hub

What I'm doing wrong?

If its not detecting automatically you would need to change the NVRAM values in a Terminal.

I used:

nvram set wan_iface=eth3
nvram set wan_ifname=eth3
nvram set wan_ifnameX=eth3
nvram set wan_ifnames=eth3
nvram commit

But I dont know if those was from the ASUS Merlin Build or DD-WRT. Anyway the ASUS should have this also.

You can get/show the values by running

nvram show | grep wan

when you have all this values you can run the above command, restart the router and it should work.

 

[numbat]

I'm using dual WAN setup
wan0 is for cable connection
wan1 for lte

After setting wan1_if*=eth3 and reboot I've tried to startup connection as I wrote in previous post, but nothing happens. Still I'm not able to obtain ip via dhcp

Here is my nvram show output

I'm stuck, dunno what should I change to make it work

I like Asuswrt-Merlin and went back to the latest build. Then I remembered, that I have a Raspberry Pi B+ box hanging around, so I configured the Rasberry Pi as a router for my Huawei E3276 LTE/4G dongle and connected Asus RT-AC68U (wan port) to Raspberry Pi B+ (ethernet).

Now download and upload are ok.

I'm still in the "testing phase" so I'll let you know how I end up with the dongle and firmware.

It sounds great. I have a lot problems with ASUS and E3272. I use Merlin, but the only working in NDIS mode version was 374. Maybe ok, but I dont have this solution. Now I use the leatest official 378 version but in that mode the E3272 it works only in PPP mode. But even with this is a problem, after a day or two the modem terminates a connection and the router haywire, resets the USB ports (I have also drive connected to the router), I have to restart everything.
How does work the E3276) in Rospberry? You had to do something if it works right away?

 

[pbefi]

How does work the E3276) in Rospberry? You had to do something if it works right away?

So far Raspberry Pi B+ has worked great with my Huawei E3276. As I mentioned I get 30-50 Mbps download & upload speeds. On full network throughput the Rasberry CPU is 80-100%.

I started configuring using this blog post:

How-to: Raspberry Pi as a 3G/4G router
http://www.g7smy.co.uk/?p=505

I ended up changing things until Huawei and firewall with forwarding was functioning as I wanted. I didn't use proxy but my firewall setup is more complex. At first I had some problems with automatic connection/dialing, but I think and hope that it is now ok.

For few months I'll try to test different scenarios to make sure that the setup is reliable.

In forthcoming weeks, whenever I have some free time, I will post here the setup/scripts I used.

 

[The Dino]

I bought a Raspberry and I'm happy with that solution. I just leeching it but the speed of the connection are great (not as in the PPP mode). I configure it yet, now it's a double NAT but I would run Raspberry in a bridge mode. So the solution is great. I'm no longer addicted on how the router handle the modem, and the Raspberry can be used for many other ways.

New version working

Hey guys!
Have some good news for you all
With this latest version of asuswrt merlin 378.50 there are some good things.
So I reverted my LTE dongle from HiLink to Modem again and gave it another try with this new build from Merlin and apparently I'm not limited to 7 Mbps anymore! YAY!!!!
Though it is still using ppptp I'm getting speed tests of already 20 Mbps or so.
I know its still not the 70 as I would have plugged to the laptop directly but, hey, its way better then the 7Mbps. And the connection is hell more stable!!!!

Hope it works for you too!
