Last year I bought three TP-link 541G+ in the unit to form a bridge mode (one master, two servants.). The first two routers were each filled with the other's MAC address. This bridge mode is very strange, at first I suspect that TP-LINK forced users to use only all TP products and set up. This time, the network is very abnormal. Upon inspection, due to the load, the main router has a dark injury, running for a period of time, ar2317 wireless chip hot. A friend on the Internet even dripping water on this chip, water dry router strike. :lol
I thought twice about it, I gave up on the 841N (overheating performance,) and bought a wr840N anyway trying to use it as the main router, and it didn't work. Because the 840N's bridging mode changed and became much simpler to just accept other people's signals (didn't test accepting other brands of routers, but TP can), but it can't give other routers the ability to exchange MAC addresses with each other. So the 840N can only act as a servant router, in other words, the old TP-LINK router can't be bridged behind the new router. I can only use a much less powerful 541G+ as the primary router. And one other 541g+ and 840N as a slave router.
Anyway, the warranty has expired, and considering the large data load required by the primary router, I've modified the original and current primary routers (both 541G+) for heat dissipation to extend the life of the primary router. I don't know why, but TP has never been too concerned about router cooling, except when it's too hot to handle, so I barely added a heatsink. Forcing customers to replace their routers means I have to DIY the 541G+.
The 1st and 2nd pictures are of the original router
The 3rd and 4th pictures are Adding a heatsink
The 5th and 6th pictures cut off the fence strip.
7 and 8 are removing the side panels (indicators)
In fact, the last picture is the finished product. The results can only be described as acceptable, the original unstable router, now only works for 2~3 days before the signal disappears,
