I have been entirely unsuccessful in backing up/restoring my units via my T-Mobile hotspot. I have confirmed that the hotspot is working fine, as my friends are able to connect to it and get very fast download speeds. However, anytime I connect to it via Quad Cortex (successfully, according to the “network check”) I am unable to load backups. I get the below error message every time. This issue persists across all eight of the Quad Cortex units we are using on the road. I am able to use my colleagues’ Hotspots just fine. I’m aware of the 2.4gHz requirement, and I have “maximize compatibility” selected to ensure function. I’m at my wits’ end with this issue, and really need it to work, as venue wi-fi does not always reach the stage.
any non-standard characters in the network Name?
Nope. “iPhone”. Again, the network is found, and I can connect to it fine. Signal is strong. Just get nowhere with backups.
Because you say other hotspots are working, the problem appears to be with your phone. So the below may not apply. AI states the following:
“This is the most reliable fix.
-
Go to Settings → User
-
Tap Log Out
-
Reboot the QC
-
Log back in with your Neural DSP credentials
This forces the QC to request a fresh API token.”
The AI also made these suggestions for an iPhone:
“iPhone Fixes (Most Reliable)
1. Turn ON “Maximize Compatibility”
This forces the hotspot into 2.4 GHz mode.
- Settings → Personal Hotspot → Maximize Compatibility → ON
This alone stabilizes the connection for most users.
2. Keep the iPhone screen awake
iOS sometimes reduces hotspot power when the screen locks.
3. Disable Low Power Mode
Low Power Mode throttles hotspot performance.
- Settings → Battery → Low Power Mode → OFF
4. Turn off “Limit IP Address Tracking”
Some users report this interfering with QC authentication.
- Settings → Wi‑Fi → (Your Hotspot) → Limit IP Tracking → OFF”
thanks for the reply. Unfortunately, all of these conditions are already met (with the exception of “Limit IP Address Tracking”) which doesn’t seem to exist in any of my Settings menus. I’ve logged out/in on the QCs many times, as the error message tends to also log me out.
It could be T-Mobile filtering your network traffic and blocking the QC because it doesn’t look like “normal web browsing“.
When your colleagues connect to your hotspot and check download speeds, they probably used their phones and downloaded something from a web site, which wouldn’t be blocked.
I did a quick web search and found T-Mobile “Web Guard“ and “Advanced Cyber Security“ as filtering features in some plans.
I’m not a T-Mobile user myself, so I can’t give any more details, but maybe you can see if these apply to you and try to disable them temporarily.
I don’t see any controls for “Advanced Cyber Security” but “Web Guard” is off. I’m out of ideas here. The most annoying part is that my buddy whose phone I used to do the backups is on the same exact T-Mobile plan that I’m on.
Hm that’s a tought one. But it seems we can at least narrow it down to either:
- Different settings for T-Mobile. (though I couldn’t tell what else to look for if not the security stuff)
- Different device capabilities or settings on the phone.
Which phone models do you and your buddy use?
@Dryicekills Some additional suggestions:
Go to Settings –> Cellular → ‘Cellular Data Options’ –> ‘Voice & Data’. Switch to the “LTE” setting and then turn off ‘5G Standalone’.
Not sure if the following setting will help or not. You may want to try the previous suggestion first and then tack this next one on if you still can’t connect reliably. Go back up one level in Settings, go to ‘Data Mode’ and select “Standard” instead of “Allow More Data on 5G”.
All these settings should be on your iPhone although some T-Mobile plans or phones hide certain options. Btw, the ‘Limit IP Address Tracking’ setting, if not hidden by your plan or phone version, should be under Settings → Cellular → ‘Cellular Data Options’. If there, per my initial post, turn it off.
