USB internet option for tethering greyed out. How to fix it?
Under Settings → Wireless and networks, USB internet will not highlight nor will it let me activate it and therefore, I can't connect my smartphone to the PC.
Is there an alternate way to check why this is occurring and fix it?
For what purpose do you want to connect your Android mobile to PC? For USB storage you need to use the Media device while connecting your device to PC.
Please make sure your data cable is functioning properly. There are also some USB cables that are not for data use. Perhaps try a different cable. Please also specify your device/OS/PC OS.
Don't know why I can't post an Answer but for me it was USB-C. That little USB is flippable, you can use it upside down or right side up. I plugged it into a regular USB adapter to plug into laptop. Well regular isn't flippable, and the adapter doesn't cover that; flipping the USB-C and then plugging it back into the adapter fixed it.
I wrestked with greyed-out' USB Tethering' for 3 days. I factory reset, changed VPN settings (when for an unknown reason I lost Data capacity), read all the forums, etc.
Its embarassing. Despite having a $40 , metal-braided, multi-tipped cord with amazing mall-metal jacks that works for charging, for Tethering it wouldnt. Trying the $3 cord I had to the same effect, i discovered it was the cord. Thays all.
The expensive cord obviously isnt made to do anything but charge, and the cheap factory cord was simply defective. (When I wiggled the wire where it gies ibto the hack, my phone beeped and all the charging/thethering options appeared.
That whole time it was the cord, poorly manufactured or damaged.
Try a brand new cord before you tear your hair out. Its likely just that. (My defective cord was only 1 day old!)
It was my usb cable which was causing the problem, I changed my USB it started enabling and disabling the option seamlessly.
I had a similar issue sort of. My Dell laptop was connected to a dell docking station via a USB-C connection. I had the phone plugged into one of the USB ports on the docking station. In trying different cables, it was a bit difficult to reach around the back of the dock so I started connecting to the laptop directly bypassing the dock. Every cable worked when directly connected to the laptop. Every cable did not work when plugged into the doc. Go figure.
When "Data saver" is turned on USB Tethering is not allowed. Turn it off and you may be able to USB Tether (Android AOSP 7.1):
- Data usage
- Tap "Data saver"
- Tap "Off" to turn it on.
You're steps may be different, you know the OS guys like to move the cheese: (https://www.quora.com/Buzzwords-What-exactly-does-Who-moved-my-cheese-mean)
I faced the same problem of USB tethering option being disabled when I updated the software on my Samsung Galaxy On5.
The solution was simple though.
When you connect your phone to the PC with a USB, a message will pop up on your phone "Allow access to device data - An MTP connection will be established to access the data on the connected device - DENY ALLOW " (Please note this message did not pop up prior to the software update...which means the phone was directly connected to the PC via USB)
When you select the ALLOW option on this pop up, then only the USB tethering option will be available for selection. If you select DENY, the USB tethering option remains disabled.
This turned out to be a hardware issue. Tried a couple of cables, but they were all the same. After removing the phone from its case and blowing in the connector and trying again it showed up. Presumably the charging pins were OK but there was some crud on the data pins (or maybe the case was not letting the plug go all the way in).
