after the latest window 10 update on the 31/11/2017 (30th? 29th?). my huawei e3372 dongle stopped working. today i got it to work again. here's what i did.. went to my internet browser history > went to last known date dongle was working (it doesnt have
to be when it was working. as long as you can find the dongle ip address. usually its written on the dongle itself. mine isnt on the dongle so i had to use this method instead) > found it.. 192.168.8.1 ..copy it down.. went to control panel > network and internet
> network and sharing centre > change adapter settings.. right click icon that represents my dongle, the one that says "remote NDIS based internet sharing device" > properties > select internet protocol version 4 > properties > check "use the following ip
address" > ip address = 192.168.8.100 (the first 7 numbers should match the dongle ip address. if you found your dongle ip address and it reads abc.def.g.h then enter abc.def.g followed by .100 into this box. since mine is 192.168.8.1, i entered 192.168.8.100)
subnet mask = 255.255.255.0 default gateway = 192.168.1.1 (the number at the rightmost side should be a 1. if your dongle ip address is abc.def.g.h then enter abc.def.g.1) > check "use the following DNS server address" > preferred DNS server = 8.8.8.8 alternate
DNS server = 8.8.4.4 > check "validate settings upon exit" > click ok > DONE. you can check that its working by going to your internet browser > go to last known date dongle was working > click your dongle address link> or you can also remove and reinsert
your dongle> DONE .. this workaround is a combination of mariqtasheva's and kalski's workarounds.
update: i tried leaving prefered DNS server and alternate DNS server blank. it still works. Hope you guys with this issue will have it resolved. = )
