Help! Wired Internet Connection using Ethernet to micro USB...

Hi Matt. Well, it looks like more info is finally coming to light. I tried your idea of connecting the Nexus to my computer (mac) via the USB, and although it needs Android File Transfer on the mac to recognize the Nexus, it works flawlessly. Uses MTP mode on the Nexus.  All the Nexus Data is visible on the Mac and even gets recognized by iphoto using PTP mode on the Nexus. Also, I noticed that the Nexus recognises the connection and shows what looks like an Android icon in the top left menu bar when connected. This would lead me to think that the USB connection in the Nexus isn't the problem, although as I said, I'm not an expert in these things.

I also tried your UI System Tuner tweak. It did exactly as you said, but when I got to notifications, they were all already on, including Ethernet, so other than having a little more flexibility with the UI, I don't think that has got us much further. Interesting though.

That leaves Nexus settings, or a faulty adaptor. The initial reason I didn't go for a faulty adaptor as the culprit was because when one adaptor stopped working (slighty loosened mini USB connector), I bought another very similar one but then couldn't get that one to work either. I suppose it is possible that the first one broke and the second one arrived already faulty. Not my first guess, but perhaps in the light of the above info, it might be what happened. Not surprising in a way.

The only other option I can think of is settings on the Nexus. I am aware of USB Debugging needing to be on, have heard various info about whether to turn on Airplane mode or not (tried both), and now in 6.1 there's the USB mode choices - Charging, MTP, PTP, RNDIS, Audio Source, MIDI, of which I have tried all but the last two, without success.

What are your thoughts to do next, given the new info above?
Again, I very much appreciate al your help with this.
Regards,
Paul :-)

I'm flying blind here, my next suspect would have been the cable on the adapter where it is attached to the plug, but with a new adapter the only other thing I can think of is to try a otg cable extension to the adapter. Or one like I linked to above that has otg baked in and specifically mentions compatibility with the Nexus 7. If you plan on rooting, you will need to unlock the bootloader first which will wipe user data, so a factory reset could be an intermediate test.

matt:
Try searching for a forum or guide for the Ethernet device you have to see if there are user issues or solutions specific to that model?

Hi Matt. I've been looking around for Micro USB to Ethernet Adaptors. I'm finding that all of them seem to have a problem on the Nexus 7 running Marshmallow, including the one you suggested in your link above. This appears to have started around Android 5/5.1. This is starting to look more like a Nexus/Android issue at this point. I read that Google sometimes denies access to certain code blocks, one of them being the USB/Ethernet scanning block.

I'll try the 6.1.1 update route next, to see if they've put it right there, and let you know what I've found...

Hi Matt. Just thought I'd drop a line and let you know I've found the solution to the lack of connectivity using the Ethernet cable - it WAS the adaptor! So I had one broken adaptor, a new replacement which came non-functional (cheap chinese make!), and then months with no connection. The adaptor that worked - and was guaranteed to by the maker - was the BobJGear model. Expensive, but great that it's 1) guaranteed, and 2) that it actually works.
So thank you for your input and help in all this. Hopefully it might help other folks look at their Ethernet to Nexus adaptor and save them a shed load of time working it out!
All the best,
Paul :-)
