SpeedStream 4100 is a router made by Siemens that, simply put, allows users to connect to the internet. Its specialty is that it can support ADSL2+. It looks like a small black box that can be placed in a dark corner of the room. On the front of this router you can see LED lamps that show you how strong your connection is. Every other information on how to use SpeedStream 4100 and the way it works can be found in the Siemens SpeedStream 4100 manual. Many users who tried to use the Siemens SpeedStream 4100 said many good things about it. The only bad thing we have to mention is that if you, for example, go on a summer vacation for a month or two, the modem will reboot and overheat because it will not be properly ventilated. But despite this, it has other great advantages. As an example, it can be used on older Telstra hardware and will work properly. Probably the best thing about it is that it’s very cheap and you can get it easily. Many people are selling them online, so the best place to find one is on eBay. When you use this modem and you have problems with the connection that can sometimes be very annoying, you should restart the router: you can do that by turning it off for about half an hour and then turning it back on. Any other information about this router and comments of people who have used it can be found online. DOWNLOAD SIEMENS SPEEDSTREAM 4100 USER MANUAL HERE
