I recently got my Razr and I was wondering if there is a way to force the hotspot to do wireless N connectivity by default and not the standard slow wireless G speeds of 54mbps....
I have already rooted the phone but the usual app I use to create a hotspot (Barnacle) doesn't work on the RAZR at all.

Someone correct me if Im wrong, but I believe the hardware limitation to mobile Hotspot only allows speeds up to 54mbs (G).

But why is it that when you activate your wifi you can cruise at a cool wireless n speeds of 100mpbs+ . yet if you create a hotspot on your device it operates only on Wireless G?

That unfortunately I do not have an answer to. Maybe someone else will have an answer for you, or a can find some techincal specs about it for you. Sorry I was not more help.

Not to sound rude, but I'm curious where you think you would "cruise at a cool wireless n speeds of 100mpbs+" regardless of whether you are using G or N? The highest 4G speeds I have seen came from the video on this site, where 52mbps was accomplished, and that was only in one test. The rest from the barrage fell much closer to 30mbps iirc. I personally get 15-20mbps and from what I have seen that would seem to put my area (Cleveland, OH) above the average. Given a realistic maximum expected throughput of 30mbps and the fact your phone will also be consuming some of the stream, I can't see any benefit from having N besides increased range, which would actually be counter-productive for carriers as it would make hotspot mode even more feasible as a home internet replacement.

As to why it might be limited, there are many possibilities. Assuming it is purely hardware based, I could only imagine the radio can only handle a sustained throughput that is not great enough to run multiple devices through it and remain stable. From the hardware integration side, that could make it much more difficult to enable using N for hotspot you could have an N mode driver that is not able to handle multiple devices connections or is not able to handle passing necessary information for some reason (although the latter is pretty unlikely). It might also be restricted by the kernel, which we can not do anything about until the bootloader is unlocked (join Operation:Mosh to help get it unlocked).

To the first part: I believe u missed that he's talking about cruising at 100mbs over wifi, not 4g.

To the second part: all sounds quite reasonable. And yes #OPMOSH is important to get an open bootloader sooner rather later

Thanks for clearing that up! But that makes sense that there's a hardware limitation possibly
