For those 4G TouchPad owners and the rare TouchPad Go owners who have upgraded to a Sierra MC77X0 series PCIe wireless card, are you showing 3G or H+?
I recently had a conversation with webOS forums user, NewbyJE, about this very topic. After doing several speed tests and swapping my APN (I'm using a prepaid T-Mobile SIM) to fast.t-mobile.com from wap.voicestream.com I was able to get about 16Mbps down and around 7Mbps up. Not too shabby. However, according to my dmesg.txt, til.log, and wan.log, NewbyJE determined not all was well. webOS never seems to believe that I am connected to speeds worthy of an H+ icon and only ever shows 3G. Yes, this is only an aesthetic problem but there are roots to a deeper issue.
This is what he had to say, "WebOS shows the 'H+' icon when connected at the Ericsson HSPA Evol speed ("networktype":"hspa-4g" in the WebOS wan.log). Specifically, the 'H+' icon is selected when the connection speed exceeds normal HSDPA (3G) speeds; the selection shows up in the til.log as the '4G icon'. I do not think the selection has anything to do with the band. Therefore, I suspect that you are not really connected at LTE speed, or even HSPA speed, if the '3G' icon is showing up".
He further recommended to take my phone's SIM out (presuming of course that I had one but that's beside the point) and use it in the Go to test a proper H+ or 4G SIM/APN combination. I couldn't do that so I took out the Go's T-Mobile SIM and popped it into my Veer. No kidding, H+. APN was wap.voicestream.com (the same APN my Go autoconfigured originally). Took it out and popped it back into my Go...3G. Hmmmm.
As I type this I wonder if there's something hanging back from the Ericsson being in the device. Perhaps a doctor? Don't get me wrong, I hate doctoring needlessly but I'd really like to nail this down. Anyone have ideas?
