Siemens Speedstream 4100b Firewall?

Recently purchased a replacement 4100. Included literature said it was a 4100b and an upgrade to the 4100. (No visible external differences noted.) Among the features listed is a "stateful inspection firewall". I think I understand stateful packet inspection as applied to firewalls. (The firewall tries to verify open internet connections that correspond to the packet. If verified, the packet is allowed through. Otherwise it's rejected.)
Questions: My ISP provided the original 4100 and did the installation. Did the 4100 have a firewall or is this an upgrade for the 4100b? Is this firewall safe to use with the built-in Windows XP firewall (the way a router firewall is able to work seamlessly with the XP firewall)? Thanks.

I had a Siemens Speedstream 4100 AQDSL modem and the switch went bad. I purchased a 4100B, but it does not work. Any suggestions.

You need to set it up according to your Internet Service Provider's settings. The Default Gateway for the modem is "" type it on the internet explorer's address bar and you will be able to access it. Now, contact your internet service provider to assist you with the configuration of the modem. It needs your Username and Password, which were both provided by your provider.

I hope it helped you. Rate for this information will greatly be appreciated. Thank you!

Siemens Speedstream 4100B DSL Modem

is the modem still new? if you have purchased it along with your dsl service from your ISP, then they should be the one to give you the warranty. however, if you bought it from best buy, walmart, etc. then you may not receive any warranty from your ISP, but you can let them replace it (especially if it's still a few months from the date of purchase) as for the phone no. well, these centers (for sales, billing, customer service, maintenance, etc.) work only during normal business hours, the ISP tech support is the one working 24/7.
here's their site:

and may I ask, why did the tech said it's defective? no power light? if the power light is on & the rest are solid lights or blinking (regardless if it's red or green...), the modem is still ok, it just doesn't have sync, but if power light is off, after plugging it from another power outlet on the wall, then that's the time when we can say it's defective.

here's the support no. 1-800-241-4453 or write them @
or at:

Siemens SpeedStream 2614 Router

Updates for this model were probably discontinued some time ago. For basic routing functions, you don't really need to upgrade. If you want this router to provide some basic firewall functions to protect against hackers on the Internet, it would be best to upgrade to one of the inexpensive LinkSys, Netgear, or D-Link routers that have improved firewall capability.
