using TL-MR3220 with same DIY enhanced E1762 antenna, the speed pretty much better than direct E1762 USB to windows 7. Although Signal Strength just 32% - 38%. Will make another antenna like TS did & compare which better biggrin.gif tongue.gif

just amazed by TP-Link 3G router biggrin.gif

TL-MR3x20 signal bar indicator not really important, good/strong 3/3.5g signals doesn't = faster speed, still depend on the isp location's free slots.

guys, i need some advice.
i just got this TL-MR3420 last week.
i use huawei E367 to connect with this router, success.
but, my internet speed drop. tested on speedtest.net, i can only get 900kbps. ping also increase.
normally without using this router, my speed can easily reach 8mbps.
my i didn't move my modem as i using an external usb cable to connect to router & pc.
why would this problem happen? or there's any setting that i missed?

my 3220 having the same problem too, latency ok but speed just drops about 2/3 compare to usb modem on laptop. flash to newer firmware doesn't help either. hmm.gif

TL-MR-3220 work flawlessly with my new Sierra AirCard 320U LTE modem, at first I was thinking need to find the additional modem bin file as this 320U modem did not listed inside tplink 3g modem work list. End up, just plug N play. biggrin.gif rclxms.gif

the 3G signals part (from MR-3220 console), 320U keep showing 35% , while E1762 jumping btw 19% - 25%.

Now only a question left, unsure if MR-3220 will optimize the Sierra AirCard "Tru-Flow" feature compare to direct USB modem onto laptop.

is there any Huawei Mobile Partner dashboard version 20 above support USSD ?

at the moment using 11.302.09.01.539_Voice_USSD, mix driver 2.0.6.718 from e376


also, the huawei driver from dc-file modem RSSI reading is much more accuracy than orig e1762 driver tongue.gif
