Something related to your modem

May I know what modem you use?

You need serious help.

List out your situation

1) location
2) modem used
3) did you set the parameters correctly.

I see a very serious problem for you now

I can confirm one thing that your signal is very bad
Second thing in this kind of location you shouldn't use that kind of modem

Solution is to use an antenna
A complete solution is buy an antenna + a good modem for signal reception + a router to share the connection.

If you having low budget, go for the antenna route first

Unless your OS having viruses, else it is unrelated to your computer

If connection drop to GPRS then 99% is caused by bad signal

What is your signal in RSSI

Kindly check at Setting > Status > Diagnostics

what kind of modem is that?

Huawei ? or just a MiFi, care to show ?

I guess you should at least buy a E1762 or E220 to do diagnostic or if you have the budget, get a E372

then we can help you to achieve good speed

trust Thread Starter, he have wat it takes to make your connection smooth and fast 

He is using Huawei E5331 which is one of the modem successfully went into my blacklist

No antenna port
Bad speed
Unstable

Sell the modem. Use the money and buy a Huawei E372 and a panel antenna

I will bring in some portable router soon

bring it back to Maxis and exchange for a Maxis Branded E372, then buy a Panel Antenna from TS, then your speed will be stable. 

If you have cash to splash, buy a Vigorfly200 for rm300, they you can fly

if u need it for most of the time on "mobile" easy to move around,

guess not much choice left

either huawei E355 / ZTE MF70 + power bank

or

any usb modem like Huawei E372/Huawei E367 + Hame A1/A100

or

any usb modem + TP Link MR3040

Oh wow, is it really that bad?
Any other MiFi you can recommend?

Signal is not everything, but direction does play roles.

Good thing abt E372 is that you can use MDMA ( V11~latest) to chk your area's signal (RSSI) and also your Cell ID.

With this info on hand, you can knoe exactly where to place the modem to get better signal , by using an extension usb (USB3.0 better) cable. A TP Link MR3420 would be much better as the Router will sufficiently power the Cable  and Modem with 1A of electrical power ( if via usb port of the pc/lappie ~ 0.5A only)

Your current MiFi is power by battery, the lower the battery the signal will degrade , hence the speed sucks.

In areas where signal is not that good, esp East Malaysia, MiFi is not suitable because the signal is not as strong like some Metro areas of West Malaysia , namely Muntri st Area ( Penang ) PJ area ( Selangor) Dengkil/Nilai ( Near Putrajaya) and ofcourse Putrajaya itself. What more a MiFi's battery will slowly degrade as usage gets longer hence the signal also degrade and speed plunge.

E372 have antenna port to accept External Antenna to boost up the signal, you can use a Panel Antenna to get better signal/speed. Its easier to use compared to a Yagi where you have to point directly to the Tower location. I know a case where the user use an Antenna Signal booster to s"suck" signal 20KM from the tower, He spent a few thousands to acquired the relevant equipment because if not he would have to drive 25KM from his home to have internet access  and you knoe those roads in East Malaysia kampong is not that good too........

That booster is really g*y
