But, my K4505 used to very high speed in same place,
and I tried to flash E182e firmware into my K4505,
as a result, my K4505/E182e become high speed again, in same place.

can you make it clear what is the actual problem u are facing ? firmware cross flashing is never ever right... so if possible install the latest k4505 rom to the modem/ speed issue may be service provider problem..

My problem is my K4505 get slow speed,But if I flash E182e firmware in to K4505,It will get fast speed and disconnect frequently,in same place and same ISP.How to let my device get fast in K4505 orget stable connection in K4505-E182e.

donot cross flash the roms, i repeat donot. use the original and latest k4505 rom . then see what happens. speed dosnot depend on what f/w the modem is on. so check the mdem settings . also what isp u are using ?

Thank you for your concern,
I flash back to K4505 latest firmware 11.870.02.10.11,
as a result, I got slow speed again,
but I find K4505 another firmware 11.828.03.01.11,
I flash it into my K4505 and I got great speed and connect frequently again.
