My apologies if this is not the correct place to post this, but I am rather desperate at present.
Will converting the modem to use serial port drivers improve the throughput on the E3131?
Can anyone recommend a Windows terminal program that will allow you to connect to the modem using the usb ports?
I am using K4605, K3772-Z, K3765 and E1752 modems with Vodacom and Cell-C sims and all of these modems give me download speeds of 3Mb/s and higher. Signal strength is between -77dBm and -71dBm on all modems. K4605 with Vodacom sim gives me better than 15Mb/s download. Even my Iburst modems gives me better than 800Kb/s download.
I am struggling to get 500Kb/s download and 300Kb/s upload with the E3131.
All these tests have been done in the same location, with the modems laying in the same area on the desk, orientation of modems are similar and they are connected to the same Windows XP SP3 notebook and Windows 7 Professional SP1 desktop.
I cannot see what the signal strength in dBm is that is being reported by the E3131, but the HiLink monitor reports 5 Bars 3G signal strength. I've bought four E3131 for a client but I'm pretty sure he is not going to be happy with the throughput on the E3131 as it is right now.
Any help to improve the throughput (short of installing antennas, as this is a portable mobile solution) will be greatly appreciated. Besides, the signal strength and quality is good enough for the other modems to download at up to 15Mb/s.
