I have an Ericsson H5321gw 3G Wireless WWAN device in my laptop that I'd like to get working, but I am in need of some help. So far, I have successfully got the device to appear as a wwan device by patching CellPhoneHelper.kext with the correct idVendor, idProduct, etc.. I setup the correct apn for my service in network settings, "connect", tried both the Generic and Sony Ericsson profiles. However, I have not been able to connect yet. The console is reporting errors from pppd; "LCP: timeout sending Config-Requests", which then results in the connection disconnecting again. Is anyone able to help me solve this problem so that I can successfully connect? Thanks in advance for your help. It will be greatly appreciated. PS: This device works perfectly when used under both Windows 7/8.1/10 and Ubuntu 15.04/16.10. Here is the output from my console:
