Over the weekend I gave the following JB modems a thorough going over...
LS8 stock JB
LS9 stock JB
NELS1 H3G Italy/UK
BULS1 Vodafone UK
I flashed and used them in 2 different locations. At home with a good H signal and at the Twilight Zone pub with barely a signal of any description. Neither of these locations has a H+ signal.
Not only did I flash them in quick succession in each location, as signal strength may vary throughout the day, but I also left each one on for a period of time. Monitoring was done with
Network Signal Info on
LS8 and
LS9 and on Settings > About device > Status on
NELS1 and
BULS1 as these latter 2 do not give accurate readings on NSI.
Long story, short... there was nothing what-so-ever between them for me. Zip, nada, nowt. In fact, if I hadn't known which modem I had flashed I wouldn't have known the difference. All worked well in both locations. This surprised me with the Vodafone
BULS1 as I had given it one quick go about 2 weeks ago at the Twilight Zone pub and felt that it was not up to the job. However, on both Friday and Saturday, all worked identically.
So. at the moment, it really doesn't matter which modem you are on. The only caveat I will add to that is that I was not able to carry out the same comparisons in a H+ area.
