WE826 T-2 with Sierra MC7455 on verizon much slower than factory 8800L modem

Post by smallmunster » Fri Feb 15, 2019 1:41 pm

I just bought a WE826 T-2 and a Sierra MC7455 to use with an unlimited Verizon data plan (government issued) and the speeds are much slower than the factory supplied mifi. On the 8800L Mifi I can get speeds around 30 to 40 down and the WE826 is at 10 down. This is sitting in the same spot.

I originally tried the Goldorb firmware and couldn't get any internet. Switched back to the OpenWRT and the wireless was working albeit not real fast. I tried using the internet through the LAN ports and it is also not working currently.

The only settings I changed are putting in the APN (VZWINTERNET) and syncing the time to the connected computer.

I was hoping to use the WE826 to provide internet to the building it was in as well as shooting it across a lake to another building with an antennae connected to a LAN port. The Mifi 8800 doesn't provide any LAN ports. I checked the internal connections and they seem tight. I am new to this and have no idea if there are any other settings that need to be changed? Any tips would be appreciated.

Can you share your signal stats?

Did you follow THIS build tutorial?

The OEM OpenWRT uses PPP to run the MC7455 which is severely limited on speeds.

Download and install the GoldenOrb firmware in THIS tutorial, and be CERTAIN to UNCHECK the box to Save Settings while you are uploading the new router firmware.

Once it is installed, Hard Reboot (power off, power on) the router, and then reset your MC7455 to OEM status following the same tutorial.

Reboot again, and set your APN, Password and Time Zone, and hard reboot the router again following the first listed Tutorial.

I have been working in this at home and followed the tutorial. Things seem to be working, but my signal is much worse at home so I will have to try it again when I go back in next week. Mifi is about 8 mbps down at my house and the lan port was the same when I was connected. The wireless test half that.

When I am connected it show I am connected to two networks, ROOter and one that is named verizon_8800L (ROOter). Is this normal or is something wrong?

These are the stats from my house:

Went to work and started over and followed the above tutorial. Stayed in QMI mode, tried to switch to MBIM before and it stopped everything from working. Verizon mifi download was 30. WE826 is around 4 to 5 mbps. Sitting in the same spot. Below is the status.

Without anything else to try I am thinking about adding better antenna's than provided with the router. Any recommendations on which ones to try? The Cisco antennas that are listed as an upgrade only have 2db gain. Is that correct? Is there a better set up to try?

I have discovered that the wireless output of the router is usually significantly less than the LAN ports. I took the unit up to the building where I want to use it and with the right placement the wired connection would consistently be around 25 mbps download. Wireless internet would anywhere from 1 to 15 mbps sitting in the same spot (widely variable most of the time).

I have it on my desk in a poor reception area (different building) and wired it will run between 5 and 8 mbps most of the time. Unplug the ethernet and connect wirelessly and it is between 0.5 to 1.5 mbps.

Would an access point plugged into a LAN port give better wireless speeds than the supplied antennas?

As an experiment I connected to my office Frontier DSL connection. Wired was around 12 to 13 mbps, wireless (through an access point) was 11 to 12. Very little drop compared to the WE826.

I saw something similar when I used the Mofi 4500 device (which is basically the same thing as the WE826).

Anyways, I recall seeing else where on this forum, that some users fixed this issue by lowering the transmit power of the AP on the WE826. You might try that and see what happens. If I recall correctly it somewhere around 15 dBM or less.

Alternatively, if that doesn't fix it, you could connect another AP via ethernet to it, to solve this problem.

After more experimentation I have figured some things out.

I found a ubiquiti nano m2 and used it as an access point. Speeds are the same as plugged into LAN ports.

I was messing around with the router and found that when I took off both 2.4G antennas the speeds went from under 1 mbps most of the time to 5 to 8 (similar or the same as the LAN ports in my office). Do nothing but put the two antennas back on and back to under 1.

I tried lowering the power to 15dBM and 10 dBM and that didn't solve anything.

I have no idea why, but the 2.4 g antennas are killing the output speeds.

One thing I just realized is the Band 4 downlink frequency you are connected to is 2350mhz (I looked this up here: http://www.rfwireless-world.com/calcula ... lator.html by putting in the LTE rx chan, FYI normally it doesn't come out the same number) is really close in frequency to 2.4ghz ISM band.

I suspect they are probably interfering with each other when you are downloading, hence the poor performance on Wifi, but not on wired. This is called adjacent channel interference, and quite common (https://en.wikipedia.org/wiki/Adjacent- ... terference) This is also why you see better performance when you physically took off the 2.4ghz antennas. You could try and change the channel to channel 11, if you haven't already (As that is the top of the band, maybe it will not interfere with the 2350mhz downlink channel?) Or if the WE826 T-2 supports 5ghz, use that?

Did you setup a Nanostation M2? I have a few of those for connecting buildings on my property, I wouldn't use them as a in house AP though. I have two Ubiquiti AC lites that are great.
