Additional power for USB modem

Hello,
My 4G USB modem (Huawei E3276) behaves a little erratic when I connect to my 4G wireless router (TL-MR3420), but works well when I connect it directly to my laptop. When I googled for solutions, I observed it could probably be because of insufficient power generated by the router. In this site http://www.ofmodemsandmen.com/powert.html it is suggested more power be supplied through a Y USB cable. I would like to know will this harm the router anyway? And if anyone else has tried something similar?

Yes these work fine and will only give the power the modem needs and should not cause any problems.

Routers often don't; have the power handling needed for these purposes.
