The upright deisgn of the Huawei HG521 router is a commendable aspect.It may not look ultra-modern but its simplicity is the reason why most people are not intimidated to use it.Because it stands vertically, it is easier to find the right spot where the router can be placed. It can be put right beside the desktop computer monitor or in a small corner. Its measurement is only 118.4mm x 90.3mm x 40.4mm.
