oh mine setup all running 24/7 like yours too,

but i do put a fan blowing at it,..

bro,
if need put fan..dont you think it is suck modem

nope, seriously all DC-HSPA+ modem is really very hot inside on the panel heatsink,.. if u open up all cover, u will know it is all similar hot temperature,

why some modem didnt feel so hot compare to other, because of the cover quality built. it able to resist on heat more than others,

zte mf680 know as hot but actually E372 is equally hot too,. ( under both open cover tested by myself ).

the higher performances = the more power consume = more heat generate

so if need to put fan doesnt mean modem sucks ( similar standard to pc /laptop )

if pc and laptop need fan /water cooling/ thermal plate = meaning it sucks too ?

if they know as least built a mini fan inside like pc or laptop lo...
extra power just for that purpose eat space, messy and waste energy
after tweakin and done all abve..result still same

have u call maxis to reset your line before ? just a simple reset ?

so u ever bring your setup to other area to test ?

like blactubi , he go to near jetty and his speed improve a lot, even on huawei E355 single channel modem

try to get an usb extension cable , try to place you modem to exactly the location where you direct plug-in to PC and see how .

for mine , if I direct plug-in to router my speed sux too cause the router location got bad reception , which is why i use the usb extension to locate my modem onto sweet spot

if without the antenna, yes all my modem need to standing up straight. Other position result sucks a lot

but u got use heatsink right?
i don't use any... and currently on 33.. safe?

speed did improve

mine one must put horizontal with purple led facing downwards , any other position/direction really got no eye see
yup u are right about antenna , it is just that my room not in favor of antenna

best just plug your zte mf680 directly into router and move together with the router to best spot,..

router + modem need good fenshui too

wifi speed & ping is sometimes lower than lan cable connection plus wifi have more interferences

I've flashed my MR3420 with openwrt two days ago. all went well, but the internet connection seems drops by half. while using stock firmware, I'm able to get download speed between 8 - 9 MB/s. Now seems I only can get between 4.xx MB/s or 5.xx MB/s if lucky. is there any settings that I missed? I followed your guide on first post.
if i revert to stock firmware, the connection seems back to normal. the only tweak i did was egress and ingress bandwidth set to 100000.

am using maxis unlimited plan.

OpenWRT known for forcing modem to Auto Band which causing it to connect to a 900 Mhz tower which would slow down quite significantly

Suggest chuah sifu to put at first post. Huawei E372 or any 900Mhz modem users are warned

so does my huawei E367 then, i guess.. can we set it to not forcing Auto Band?

Done, thanks for that reminder,.

yea now u know why i use V2 + V1 both together ?

I believe it is due to modem orientation
