Main route (good performance)

Secondary route or switch ()

Wireless APs

Hard-to-change routers
In fact, the route is very simple, a CPU, a memory, a flash, a few capacitors, several inductors, several MOS tubes, resistors, capacitors.
That is, as long as the LEI branch 236W CPU router, in exchange for the same capacity of memory particles, brush on Lei branch of the firmware, it is Lei branch.
There is no instability.
You send the link not to go, but I myself with Tengda N300, 837R, Lei branch 736, 735 hard to mend 236W, in addition to friends, the remaining 2 for personal use, very stable. If the N300 is changed, the heat dissipation space is small, long-term use stability is unknown.
