I'm currently running CM10.1.2-toro on my Verizon Galaxy Nexus, and every single time I tether my computer using the built-in Wi-Fi tethering option, it creates a new network. This does a couple of things. First of all, it takes forever to connect, often as long as 2-3 minutes. Second, it gives it a new, incrementing name every time (i.e. my SSID is "Droid" and each new connection it comes up as Droid 1, Droid 2... Droid 37, etc.). Third, it requires me to set the network type (Home, Work, Public) every time. I have searched around for this, and most of the answers just say it's a problem with Windows. It isn't. I had my Droid X for 2 years with Wifi-Tether for Root Users, and it never did this. This is definitely an issue with the tethering implementation on the GNex, perhaps the issue is with CM, I'm not sure. I did happen to find one thread (which I can't find now to link to, but I'll add the link if I find it), that indicated that the issue occurred because the MAC address was changed every time the tethering connection was created, causing Windows to thing it's seeing a completely new device every time. This seems to be in line with what I'm experiencing. However, the solution posed in that thread (writing the desired MAC address to /sys/module/g_android/parameters/dev_addr at boot time) doesn't seem to work. I've written the MAC address to that file and it still creates a new network every time. Has anybody else experienced/found a solution to this issue?
