Wireless Joint

Been digging deeper into the rabbit hole and noticed something when trying to pin this "drop" down. The FW rules aren't getting traffic hits where I would expect them to. I swapped rules around and moved the WWAN rules up to ensure the counts were being triggered and for some reason it appears to be ...

Played around with putting the SC card inside on the PCIE card and couldn't get a stable card initialization in either mode USB/PCIE
Something weird with that card working in only certain scenarios even with the new cables

Slab is working fine with the SC card and the same software issues trigger ...

Interesting....

The Fibocom works well as a backup but, it's SLOW
In MBIM mode / PCIE mode the modem seems to be using hotspot data and when doing a traceroute it shows the hops across TMO's network vs the IPv6 generic 192.0.0.1 in USB mode w the SIMcom

The HS data brought back to mind the TTL 65 ...

Stuff showed up and has been tested.

Slab adapter isn't working - at least w/ the FC card
PCIE adapter now works with Fibocom but, flaps with SIMcom
The enclosure works though it's a PITA to put together due to the confined space it messes with the pigtail wires when putting it back together and ...

Well, got a bill a couple weeks ago for the KVD and went to dispute it in a store to see if they would budge if saying UPS lost it. Nope.

Well they added another jab before sending it to collections by adding another late fee to the total. Went to the store again to see if they could do anything ...

rc5 has been stable and DHL has the packages.

Seems I jumped the gun while troubleshooting on ordering more parts but, it's still going to be nice to have options. With having 2 modems now I have the ability to mount one inside the server with the PCIE adapter and leave it inside w/o messing with ...

6.8.7 was pretty stable.

6.9.rc5 showed a race change for cdc-wdm which hopefully means it's stable unlike rc1/4 were not

AE shipment landed yesterday and should be processing through customs today and delivery maybe Wed. Depends on what happens when DHL hands off to USPS locally.

So, I started thinking about when this issue started and the kernel update prior to it. I had just done an update prior and a couple since it started. The issue came up though when on 6.9.rc1. rc2/3 didn't install due to an odd dependency that's for another line of linux. So, I rolled back to 6.8.7 ...

Went ahead and ordered some stuff..
Picked up the 2 items above and a couple of USB3 cables for the PCIE adapter since the one that shipped with it is posing issues when installed causing the modem to not come online and recycle. Also grabbed a FM350-GL for under $50 just to test a theory and have a ...

Been down a bit of a rabbit hole recently trying to pin down why things changed.

Normally things have been working just fine up until about a week ago. I'll be doing my normal routine and then the internet drops. OK, look in the logs and nothing is apparent. Reboot the modem and it's back online ...

RF is a finicky thing. Too much gain and not enough equal the same issue.

In the world of cable though an SNR closest to 0 is ideal.

I don't have a GUI to go off of for probing my modem so....

That's your WAN off the WWAN side.

More specifically the Gateway as your modem has 192.0.0.2 and an IPV6 address assigned when it connects to the network.

I haven't dove into phone TTL but, I did get an M2 Modem and hooked it up over USB to ditch TMHI and have been pushing 1TB/mo on it w/o any modifications to the TTL and it works just fine. Maybe it's time to switch the approach? Probably cheaper than buying phones to get the latest in terms of ...

Connecting

I just use a minicom session through my Linux box that my modem connects to in order to probe the modem directly.

minicom -b 115200 -D /dev/ttyUSB2

This gets me to the AT terminal on the modem. While some GUI is useful it's much better to directly interface with these modems to ...

test the sim card in a phone to make sure the service is working properly.

The SIM is provisioned and working per testing in the MOFI.

@CK25Hulk
The way I'm seeing this is something glitched in the modem itself or see below. I use my SIMCOM in a USB sled and while it works fine there are ...

The way I'm reading this is you have 2 ISP WWAN connections being fed into the PF box....

IMEI / MAC will be different for each ISP

I use TMO and 192.0.0.1 is their standard IP you would see on the "WAN" side. It's some sort of IPv6 xlate / tunnel they issue to the connection.
-- I started out ...

All carriers seem to be doing an all out war on VPN use on cell data. It's odd as heck.

Have you tested it ok outside of the VPN use, or tried a simpler proxy, or just used TCP only on the VPN?

Gaming services and VPNs use UDP traffic heavily, and that is seemingly what is getting messed with ...

So, I got another invoice and it's $30.50 just like above. So, that kind of settles the billing hypothesis.

$30.50/mo
$8.00/mo
------------
$38.50/mo - all in

Not sure why they're billing the "service fee" separately but, it's still $10/mo cheaper than the upfront suggested price of $40 + $8 ...

- got a final bill for $0.00 for TMHI even w/o returning the KVD still
- got a notification for the $8/mo CI surcharge which if things play out brings the all in to $38/mo which should be confirmed in a few days with the new billing cycle
- things have stabilized by pushing 2/41 instead of allowing ...

Looks like the MCC/MNC 470/02 or 202/01 varies depending on the site but also it should be using IPV4V6 and not just ...

Did you power cycle the modem after changes?

If it's still not working then do the reset to defaults and check again. It shouldn't be an issue with the provider storing the binding of the SIM and IMEI but, maybe leave it powered off for 15 minutes and then fire it up again.

Another thing that ...

Thanks @Tech_Junky, so helpful.
It seems now that the network rejects my registration.
AT+CREG?
+CREG: 0,3
Any idea why?

It could be something with the APN not being correct or maybe the SIM isn't inserted 100%. You should be able to poll the modem and get the info.

AT+CEREG?
0,3 = 3 ...

I don't know specifically but, when I try to run the COPS command while the modem is online it errors now. I found one command though that resets everything back to defaults though that could be helpful in working through the connection issue.

AT&F

I've also noticed with it plugged ...

Found a more direct route to getting 2/41 band set than toggling SA/NSA and hoping for the modem to grab the right combo.

Code: Select all

AT+CSYSSEL="lte_band",2
AT+CSYSSEL="nsa_nr5g_band",41

It also survives modem reboots.

First bill / invoice from CI hit and it looks even better than when first digging into the option.

https://i.imgur.com/i8jXuIX.png

$30.50/mo is even better than what I was anticipating based on the info at sign up. Kind of makes me want to pester them regarding the fees / price paid at sign up ...

TMO must be working on the site or need to since LTE 66 seems to be bogged down for speed. I've been chasing this all day trying to figure out why things have been slow. I bounced the modem from NSA to SA a few times to switch the LTE band while testing the speeds and found 2/41 performing much ...

Went and took care of the bill w/o returning the KVD and the prorate was ~$45. No NRF on the bill for the KVD non-return even a month after cancel. TMO is a bit odd considering the bill sent to collections but no charge yet for the GW. First full month of hammering the new modem resulted in ~1TB of ...

Interesting little piece of mail showed up today. TMO sent the bill to collections even though they still haven't sent the prorated final bill for the cancellation which was 12/21. Just one more thing to deal with in cleaning up things post mortem.

So far the voice line is doing well though with ...

So, I've had some "drop outs" where the modem shows activity but, the rest of the network doesn't do anything. Tested different cables / ports / etc. and finally caught something in the logs pointing to the "modemmanager" which goes back to not wanting to use any of the GUI based junk that tends to ...

I picked up a couple of them on AE for under $40/ea and they're the "client" option of the two Qualcomm has released so far but, most times you can activate them in AP mode fairly easy.

Kvalo on git does most of the driver work for Linux though and there have been some updates and ...

So, TMO messaged me with the NRF for the box would be $220. Which is in writing at this point if they decide to be a PITA about this. I can probably get them to push that down a bit more with some pleading. They'll get it back either way though it's just how they handle what they get back and if ...

Well, tried to return the KVD locally and they wouldn't take it because they wouldn't spend time to put it back together or refurb it and also wanted me to call in to cancel vs just doing it in store. Grabbed my toys and left the sandbox because I knew better than to battle them in person.

Got ...

Tried to change the APN on the modem and it was being difficult so did a factory reset on it and it came online w/o further configuration. Testing now to see if I need to bother with the TTL since it's showing just normal phone use on the TMO dashboard at the moment. Then again there seems to be a ...

Got the psim activated and now to reconfigure the modem and ditch the tmhi fees.

I guess this deserves a bit of a "don't try this at home" disclaimer unless you have some patience to deal with multiple parties to get things provisioned and sorted. If you have more time and a plan it's not so bad ...

After pulling teeth and hitting several locations I now have a SIM in hand for $10. If the TMHI billing period had more time it would have been easier to just order them off Amazon w/ Prime for under $5/ea.https://www.amazon.com/gp/product/B08FRR5M5Z

The SIM they handed me (R15) after putting up a ...

Hit 650 DL this morning w/ the phone. Off to TMO to get a pSIM though for the modem and convert it over.

Finally got the eSIM worked on on the phone for the new plan. Speeds on the phone are almost 500mbps DL / 65mbps UL which is about 100mbps+ DL and about double UL. Just need to head to the store and pick up a pSIM to use in the modem and make sure it works as a phone by putting the phone IMEI onto ...

I think I figured out the VPN issue. Seems for some reason it's not adding the routes when connecting. I think the app is looking for traditional nic interfaces to bind them to and the metric for the wwan is 700 when a wired connection is 0 or 1. Might have to script a lower metric assigned to the ...

So, to save time and money I had CI change the plan to Magenta Max because it's $5 cheaper and still offers unlimited 5G + 40GB of HS data. I also had them just activate it using my phone w/ eSIM to avoid the charge for shippng as I can just drop into a store once the account is setup and probably ...

Did a speed test this morning and hit 400/40 after leaving the modem in the same spot overnight.

Anywho... got an odd problem with NordVPN dropping DNS connectivity after ~5 minutes which wasn't an issue when using Ethernet to the KVD box. I don't think using USB though should be an issue but ...

Placed an order on circledin.com to join a plan for a new sim and packed up the kvd21 for return if TMO even wants it back since they just upgraded to the new sage boxes which presumably have better modems inside.

It's $53/mo with unlimited data and 50GB of tether if needed. This should unlock ...

Up and working using nmcli and since the apn is configured in the modem itself no need to add the apn in the OS. Really didn't want to use NM though and will probably find a way to make it work without it later on.

Well, Linux sees and works using network manager from live USB boot and add apn in NM. Trying to get it working with nmcli now since the GUI through rdp keeps kicking the apn add when saving for some reason. SMH

Well, I hooked up the adapter to the laptop w/ Windows on it and it's working great with higher speeds ~250/50 vs the KVD box which has been sitting around 100/40 lately. So, I've got it configured right it's just a matter of fixing Linux aka router to use both v4/v6 and get it working as intended ...

OK, got all the pieces and put together everything needed so far and made some changes to how it's supposed to vs how it works better from a physical standpoint of the parts. The USB adapter is very DIY compared to what I thought it was going to be in the listing but, not too bad.

I played around ...

So, DHL dropped everything at my PO location 2 days ago and USPS decided they wanted to give the package a tour of the city for a couple of days for no reason but, showing that everything should be delivered today finally. It amazes me how inefficient USPS can be sometimes. Adding time and fuel for ...

now I am a bit lost, anyone have ideas - please share :)
Modem has not been moved even a bit. Same place, all changes were via LAN or on carrier side.

When I first got TMHI I did some of what you're doing but went a bit further and deconstructed the box completely out of curiosity and planned ...

That's a good tip. Something I pondered to consolidate things as I've done it with WIFI setups in the past. RF is a funny creature though.

I just grabbed them since they're cheap and I might come up with something in the future with WIFI where aggregating things might be the easy option. i used ...

So, I found this site while looking at modems as an option to replace the KVD21 option. I've been pondering this since getting signed up for the past couple of years. I finally dug into it again after seeing 5G modems coming down in price when looking for something else.

Anyway, the modem should ...
