Did it work? I have ordered an LHGG but I already have this modem and I would like to know if the upgrade works
- t99w175 works only in PCI mode so it is unsuitable to be mounted on routerboards.
- Keep the LHG lte18 with its original module from ros7 you can directly update the modem firmware.
- The performance of lte18 is amazing ,then with a 5G modem you should add another 2/4 auxiliary antennas is not easy.
To be fair, i have to make it clear that I don’t own the CAT18 LHGG but the CAT6 so i could use some upgrade here.
It seems odd that the T99W175 wouldn’t work as the DW5821e is listed on the supported modems and it’s very similar to the one I am talking about.
I don’t mind about the 2 more antennas it needs to work, it’s an easy modification for me.
However if you’re 100% sure this modem doesn’t support the usb protocol I won’t event try it. I’ve seen some sellers listing it as supported by MBIM via USB. So I don’t know what to believe anymore.
