i bought mr3420 at c-zone @ rm83.

anyone of u experiencing wifi hang. my wifi hang so frequently like every 5 minute

That's because of the channel that you are using.
Try changing the channel, to channel 11 or etc. Mine is channel 6 and it works the best till this date.

Any idea how can we tell that it is because of the channel?

Download inSSIDer here - http://www.metageek.net/products/inssider-wifi-scanner/ - to inspect WiFi channel availability

Recommended channel are 1, 6 or 11 however if your house is heavily WiFi-ed, you have to test all channel to get a non-interference channel.

last year i bought mine 3420 for rm75 from my company supplier...he gv a little bit discount... just ask him , now price back to rm85

But after I switch to Bg mixed then it become ok d. so it is still the channel problem?

Monitor for a while.
I switched mine to Channel 6 and only use B/G.

hi, new to routers here,
just wanna ask what are the main differences between tp-link 3420 and aztech hw-550 3g

I have both and earlier Aztech HW-550 3G is not that flexible when it comes to modem compatibility list.
Recently, with the endless of upgrades, I can even run my E372 on it.
Speed wise, I would say both are pretty the same.

I prefer TP Link MR 3420 to Aztech HW-550 3G.

oh and do these routers get their power from wall socket or from physical connection with computer? do they have batteries?

They are routers not MiFi, so it is powered by wall socket.

lol so kinda misleading then in their websites they brag about mobility

I prefer routers than MiFi, but then the mobility is totally a minus point la.

Input voltage is 12V DC so can use car battery. Well still 'mobility' on the road or camping.

sorry to ask here, is ICON 505M supported by this 3G router? TQ

Yes.

thanks for the info fruitie helping a fren to ask as he is interested in my ICON 505M

hmm anyone can enlighten me about the QSS function?

Hi guys, does this router support e372/ e367 / sierra (i forgot which model that supports 42mbps)? Thanks ya
