I have this issue for my E1762 (not sure why)

random disconnection and very slow to reconnect. So for me the fastest way is to reboot the modem (in some cases, I have to power off and on the router).
I notice if the line (maxis) is down (due to bad weather/no signal), it will somehow hang my router

Currently using my old K3565, and so far stable for the last 2 weeks.
btw some antenna and it manage to boost up the signal from 10 to 50%

well, if u using maxis, u could try to use MDMA to force your E1762 work on single 3G band 900 or 2100 instead of scanning through out all signal available before can connect,..
u can download it
hererefer
hereopen the file u download, then plug your E1762 in your computer, and go under band config to select single 3G signal u want to use, and then click apply and ok, and unplug it from pc and plug in router,.. ur router will dialer faster than last time,..
hope it helps you outs,..
