ah yes, the router is just cold and the modem is slightly warm, i can say that it is not warm at all....but every 8 hours (i timed it inside the router uptime)

and im using usb 2.0 cable, does using usb3.0 makes a different? and how about the lengh?

br-lan is correct. The settings are correct though.

If you can't ping, then Internet Connection Sharing (ICS) is not done correctly. Check ICS again (watch Chuah's youtube video).

changed to openwrt and finally getting this result:

haaaaa!

just wondering.

is modem temperature higher when we downloading (or uploading), and remain warm when we not using internet?

can i plug and on the E372 24/7 on router all the time?

yes very noisy and have to clean the dust on the modem and router every week. if not the dust will be very2 thick....i rent a newly built house, so there is so much dust in the house...even after living for more that 5 months.....

i dont hang the modem in anyway....i just plug it in to the router directly, the router i drill two holes and put it two screws and hang the router there. just like hanging a picture frame....

the result of connecting the modem straight to the router vs using usb cable is very2 significant.....now ping stable and got better upload speed, i guess download speed is just limited by my tower....huuuu

guys, anyone had any issue your modem cannot get into hspa+ signal? im having this problem....the modem connected already and can use internet and all. but the led on my modem only show blue (3g 384kbps) led....sometimes it takes a while then it will turn cyan (hspa+) all of a sudden! sometimes it wont change at all until i do reconnection.....

when it connected to 3g (blue led), the speed is very2 consistent at 384kbps..... anyone have any solution to this?   

OpenWRT got QoS build in

If you don't mind using your time to read the whole context, here is the link

http://wiki.openwrt.org/doc/uci/qos

so using wdr4300 with e372 can get you to what speed?
