Ericsson W25 Fixed Wireless Router Introduction

A fixed wireless router means a device which is connected to the internet using a mobile network and it distributes the internet access for a home/small office network using wired and/or wireless LAN. The reason for using this kind of devices is either because where you live/work you do not have a fixed internet or simply because the price for a mobile internet can be lower than for a fixed one.

The Ericsson W25 is a GSM/UMTS/HSDPA one, it can be used on GSM or UMTS networks. The theoretical maximal donwload speed is, 7.2 Mbit/sec with HSDPA, but today only very few carriers support this and even if it is supperted you can not reach this speed. The network which I am using supports only 1,8 Mbit/sec where I live and even with this theoretical possibility I can not reach higher speed than 1,4 Mbit/sec. However this speed is almost 3 times higher than my previous internet connection which was an outdoor WLAN based 512 k connection.

Beside the internet access this device has the possibility to connect traditional telephones to it, in this case call made from the foxed phones will be connected trough the wireless network. In a lot of countries, this can save you a lot of money, when calling mobile numbers.

The Ericsson W25 was designed with the customers in mind, this means that a lot of effort was taken to make it as simple to use as possible. This was sucessfull, after purchasing, you need only to plug in a SIM card and plug it into an AC outlet and voila, it is up and running. Of course if don't want to share your internet connection with your neighborhood, you need to run trough the web based setup wizzard. The management web pages are also very simple, they only contain the most important parameters.

If this is not enough for you, then this Blog is for you, as in the next posts we will look into more advanced configurations and look into how we can hack into the router, to enable new features.

Till then I recomend you to visit this address: http://www.mobiledata.net.au/ here you can find the newest firmware, which is much more stable than the one on the official W25 site.
