Skamath, he's talking about a desktop computer needing to download, not his phone. The Lumia Software Recovery Tool will not help in either situation. Also, I have been on this forum for 6 months now, and this is the first time I've seen it abbreviated LSRT. If you just mention LSRT, the only valid abbreviation is the Louisiana Society of Radiological Technicians, so please spell it out the first time you use it to avoid confusion.
roystreet, I picked up an inexpensive portable Bridge in order to do the work for me, as I needed the same thing at one point in time. The bridge accesses the phone Internet Sharing like your computer would, then you plug in an Ethernet cable between the bridge and PC, and you no longer have a metered connection. The computer sees a wired Broadband connection. Problem solved.
I'll edit this post, or post again when I've located a link for what I bought, so that you can shop and compare. I bought mine for $18.99 on Amazon.
EDIT: I bought the
TP-Link TL-WR702N model. That is a starting point to help you see what you need, and you can search for the best deal/brand that you want. Not sure if spending more money is an option, but this did solve my issue.
I was able to plug this into the WAN port of a cheap, $12 Wi-Fi router, and now my wife and I can both have unmetered access to my phone's hotspot by connecting to the router instead of my phone. Using that method, I just turn on my Internet Sharing when I return home, and it automatically connects. That way, the Internet Sharing is always there whenever I try to use my laptop. The laptop automatically connects to the router when turned on, so unless I've left the house, I don't ever have to re-enable Internet Sharing. Plus, it gives me access to the Wireless Printer we have connected to the router, so I don't have to disconnect from the internet to connect to the printer. Nice way to set up a home network when you live 10 miles past the point of any wired internet provider's service. LTE is strong here, but that or Satellite were our only choices, so LTE is what we have.
