i have read few post about these 2 models.
e5180s-22 what they promote as CPE home grade
B310, they call it as CPE Enterprise grade.
Which i think the answer is obvious on this.
both devices have come with almost same but B310 have gigabyte Ethernet port where e5180 only come with slower type.
and i feel confused on e5180 is that from taobao, it say it have a thousand mah of removable battery but the english article they didnt talk about this.
Not sure whether which is accurate info hahaha.
I found b310 is way affordable and more outstanding in this situation. if u wan a fancy looking modem then maybe you should go for e5180 as the LED light on the top HAHA and some say that indicator is one of the disadvantage where it hard to determine the signal quality from sight
B310 unit are not come with free pair of antenna i guess. i cant find where the page link i read it said not support mimo..not sure what it means lol.
