Re: Latency Issues? (Solved: QMI > MBIM)

IPv6 works fine with QMI on both Sprint and Verizon.

Tested on:
1) GO 3-10
2) OpenWRT w/MM
3) Arch w/MM
Verizon was on the EM7565 (FW12) for all 3. Sprint was on the EM7455 (FW23) for all 3.

An interesting note is that ipv4 might actually be handled differently on verizon - I had mentioned ...

Re: Verizon Latency Issues?


Off Topic, but do you have any links to info on how to setup modem manager with stock openwrt? I want to replace GoldenOrb with openwrt, so I can have ip pass through.

I just built it using these three pages:

(Ping under load - there have been people streaming most of the time that it's been running.)

Thanks everyone for the help!
I figured out a solution - use qmi.
(That would have been a really simple thing to just randomly try before going through all the effort of actually tracking it ...

Re: Verizon Latency Issues?

Okay... it's either a hardware issue with my router or a bug in the firmware...

The following 3 tests are using a sprint sim:
1) 7455 in usb enclosure attached to the computer directly - this shows normal/low latency
2) 7455 in usb enclosure attached to the wg3526 - this shows high latency
3) 7565 ...

Re: Verizon Latency Issues?


Ugg....is there any other verizon plans that aren't throttled?


I haven't done any of this, so I could be wrong on some of it, but I looked into it when I was setting my prepaid account up last month...
From my understanding, that post you linked with the ttl stuff allows you to use a tablet ...

Re: Verizon Latency Issues?


Also, how do you do the TTL changes? I wanted to try this but I couldn't find on my version of GoldenOrb in the Network -> Firewall, any TTL settings.


That tab just adds the following two rules to "Custom Rules" (make sure it's the correct interface)
iptables -t mangle -I POSTROUTING -o wwan0 ...

Re: Verizon Latency Issues?

Okay... multiple problems with trying to check the tracerts... nothing insurmountable though.

First, on the modem, all ip4 tracerts show a total of 1 hop... I assume verizon is 4>6 natting it immediately and then I just see nothing. While that doesn't happen on the phone, it doesn't appear to be ...

Re: Verizon Latency Issues?

Thanks for the ideas...

1. Will check tracerts tonight and update.

2. I had noticed that they both dropped ca without a connection, so I tried with a background download at ~2mbps. It had no effect... but that was also downloading from a different server than I was pinging. I'm not really sure ...

Re: Verizon Latency Issues?

The router has a computer attached by ethernet cable which I'm ssh'ing from - the actual ping is being run on the router itself though.

Nothing is connected to the phone; the ping is being run in Termux.

Latency Issues? (Solved: QMI > MBIM)

Hi all -

I have a wg3526 set up with an em7565 on an unlimited verizon prepaid sim. The modem gets around the same signal strength and upload/download speeds (~15-20/75-90) as my android phone sitting next to it, but the latency is significantly higher with the modem... They are both connecting to ...

Re: Disconnect every 638-643 seconds...

All hail the rubber ducky.

dhcpcd was verifying its leases every 10 minutes (+30 second timeout) and removing the modem's ip address when no resolvers responded. I'm not sure why the first message in the system log is the modem sending a message saying that it's deactivated rather than dhcpcd ...

Re: Disconnect every 638-643 seconds...

I'm not, I got the recommended power cable with it.

I ran ModemManager and NetworkManager with the debug options; the first event during a disconnect is:

... which seems pretty worthless as far as troubleshooting goes.

NetworkManager reports the change slightly after, then reports that it ...

Disconnect every 638-643 seconds...

EM7565, USB2.0 M.2 Enclosure, Verizon, Linux...

I'm getting a very consistent disconnect about every 640 seconds, after which it reconnects pretty much instantly without further issue.

I have no idea where to even start looking... anyone able to help?

Thanks
