Currently Im using Maxis broadband. So far, its worked fine when just plugging the bb modem to single computer.
The problem is occurred when i plugged into TP 3G router (Model: TP-MR3420), all of my computers (win7) only will disconnect from the internet service (still connected, but the wifi icon got the exclamation mark and cant access to 192.168.1.1) very frequently(1-10min will disconnect once), but iphone and macbook rarely. So i have to reconnect again and again.

BB modem is E173u-1
3G Router TP-Link TP-MR3420
BB ISP Maxis
Windows 7 Pro and Home Premium

Router 3G's setting
Mobile ISP - Maxis_unet
Connection mode - Auto
Dial net - *99#
APN - unet
Username and password - blank
Authentication type - Auto
MTU Size - 1480
DNS - 8.8.8.8
Secondary DNS - 8.8.4.4

I have troubleshoot to TP, but what they told me is the TP-LINK router is functioning well.

Any pro here can help me?

Im using business plan, unlimited data. I changed APN to maxisbb, the network icon didnt show the exclamation mark anymore when i playing pps. I think ok ald =D Many thanks

too bad the problem came back again.
took a few hour to go thru all the posts, nw changed to channel auto, wil take a day for observation.
as wifi analyzer suggested channel is 11 (5stars in my area), but router auto channel is 4 (only 1 star in wifi analyzer). Which 1 more reliable?
