Slow Speeds on Speedster

Try a different USB port

It is possible there is a difference in speeds and data transfer between different USB ports. Remove the Speedster and test it in a different USB port.

Check the account

If your speed has slowed down suddenly, depending on your plan, you may have used your monthly data allowance. This can be checked by logging into the iPrimus Toolbox:


iPrimus Toolbox

If you are rate limited, it will display on the front screen.

To check your usage select ‘Usage Summary’ from the menu on the left.

Here it will display your remaining data for the month. If you have gone over your data allowance, the connection will be slowed.

To check the speed of your plan, under ‘Internet Account’ in the toolbox, the plan, with speed, will be listed under ‘Service Plan’

Run a speed test on the connection

This will tell you the speed of your connection.

Run one of the following speed tests, and note the results.

When running a speed test it is important that there are no programs or downloads running in the background, as these share the connection, and will give a slower and less accurate results.



These will give you a speed test result in Mbps.

Check your network coverage

The speeds of the Mobile Broadband Speedster are dependent on the strength of the connection it can get to the mobile network. The better the signal, the more likely you will be able to get good speeds.

To see what mobile coverage is like at your current location, use the mobile coverage map.


Modem indicator lights

The colour of the lights on the Speedster indicate what sort of a connection it is getting to the network. 3G / HSDPA connections are the fastest, and while a 2G connection is much slower, it can be more stable.

Change your network selection

It is possible to have the modem select only one network type. This can increase speeds if the modem is flicking between two network type – however, it may also make the connection more unstable, as it cannot fall back on the secondary network if it drops out.

From the Wireless Broadband software, go to the ‘Tools’ dropdown menu up the top, then ‘Options’, then ‘Network’.

Here you can set a preferred network type under the ‘Network Type’ drop down box.

Selecting WCDMA only may result in an increase in speeds.

Test in a second location

As the connection is dependent on the mobile towers, the speeds can change in different locations. To see if the slow speeds are tied just to certain towers, test the service elsewhere and note the difference.

Local computer and network factors

If the speedster has a solid 3G / HSDPA connection to the network, it is possible that software or factors on the local computer or network could slow down the connection.

The most common of these is simply high usage on the computer.

To rule this out, conduct a speed test with nothing running in the background.

Also, it is important to test another computer in case the speed issue is limited to one computer. If the speed is the same on two computers, this is an accurate reflection of the speed of the connection.

It is also possible to check all active internet connections on the computer. This can be done by using the Netstat command, and it will show all active internet connection on the computer. If this number if very high, it could be causing the connection to slow down.

Firewall, security or anti-virus software can also slow down the connection.

Disable any security software and run another speed test. If there is a significant difference this could be the issue.
