GAC-252 802.11 Lite-N WiFi Dialup Router- Share Dialup via WiFi/LAN

Note: WiFi Dial Up routers cannot increase the speed of the dial up connection !

Not Compatible with AOL, NetZero  and Juno !

More and more devices have WiFi wireless connectivity these days. Whether it's an iPhone or Android smartpone, or an iPad,  or a Kindle tablet - you name it, WiFi wireless connectivity is ubiquitous.  While you can walk into any electronics store and find a wireless router which can connect these devices to the Internet over a high speed fiber,  DSL, or cable connection,  what if all you have is  Plain Old Telephone Service (POTS) and only dial up capabilities. Sure - many of these wireless devices have cellular access built in  but what use is that if you can't get a decent signal inside your house.  And what happens when you go to your vacation home  in the mountains or a remote beach and all you have is a telehone line to connect you to rest of the world !

The GAC-252 makes a dialup connection to the dial up Internet Service Provider (ISP) of your choice. It is pre-programmed with a free dial up ISP*** long-distance phone number so that you can start using your WiFi  wireless enabled device without a subscription (long distance phone charges may apply, no guarantee is made of free ISP service availability or performance).   The GAC-252 supports the popular 802.11n WiFi standard  which provides  extended range and coverage. It allows you to be hundreds of feet away from the router  and still use your WiFi device. The GAC-252 connects via its USB port to a   V.92-standard 56K USB dial up modem (included with the unit)  to provide the maximum data rate your phoneline can support (usually 40-50 kbps for clean lines and lower for noisy lines). Need even greater range ? The GAC-252 WiFi antenna is detachable and can be easily replaced with an inexpensive higher gain antenna. And if you eventually move to a broadband service you can continue using the GAC-252  to get high speed WiFi access to the broadband service.

The GAC-252 is compatible with all WiFi devices including PCs running all versions of Windows (Windows 7, Windows Vista, Windows XP, Windows 2000, etc.), all flavors of  Mac OS, and all distributions of  Linux. Other compatible devices include all WiFi smartphones (iPhone, Blackberry, and Android mobiles), tablets (Kindle, Nook, Android, iPad, etc.) and all WiFi gaming devices like the Nintendo DS.  Multiple users can share the dial up connection using either WiFI and/or the 4 LAN ports on the router. For machine to machine applications the GAC-252 incorporates a schedule based dial out feature. It can be configured to dial out at various times of the day or week for a configurable period of time.

A dial-in feature has been  introduced which allows users to connect via the PSTN and their own modems to the GAC router at a remote location and access devices such as IP cameras and PCs.  This substitutes for Remote Access Servers which are expensive and more difficult to configure. A Python based Windows Application is also provided on the CD which allows the dial up connection to be started and stopped remotely from a PC. In addition to this Windows application, an API for remotely starting, stopping or checking status  is available upon request so that this functionality can be embedded into other applications. For even more flexibility the router can be configured with a Schedule to initiate a dialup session at a particular time.

The GAC-252 is compatible with dial up ISPs who do not require specialized PC/MAC software for dial up access and will  definitely work for you if  you  use standard Windows or Mac dial up network connections to make your dial up ISP connection today. Most ISPs are compatible with the GAC-252. On the other hand,  Netzero, Juno and AOL are some of the known ISPs that require special software and are  incompatible with the GAC-252.  

Compatible dial up ISPs include:

FreeDialup.org  www.freedialup.org
FastFreeDialup.com www.fastfreedialup.com
Copper.Net  www.copper.net

Compatibility with Dial Up Acceleration

The router has been tested successfully with Slipstream Dial Up Acceleration software and is likely to be compatible with other accelerators such as Propel. However only Slipstream has been tested to date.


Future Proofed

The GAC-252 WiFi Router is compatible with all Broadband Internet Connections (DSL, Cable, Fiber, and satellite). So you can continue using it to get great WiFi coverage and performance even if you move from dial up to broadband.

The GAC-252 is now available for immediate shipping. We have plenty of units in stock. This unit is similar to the now discontinued GAC-152. Couple of key differences are the Dial button is at the back and the USB port and reset buttons are on the side

We are working on a replacement for the GAC-152 which should be ready in about a month. Meanwhile we may be getting a few units in of the existing GAC-152. Please send an email to info@greatarbor.com if you want to be informed when the units are in.

Yes it can be used with almost all international ISPs. If standard Windows Dial Up Networking works with the ISP - the GAC-152 will also work

Hello GreatArbor;
I recently purchased your GAC152.It is an excellent product.It has not skipped a beat since day one.It was very easy to set up and works flawlessly. I used to use a Wiflyer,but that was a tonka toy compared to the GAC152. Thank You...Len

I love my GAC 152! It works great with my dial up ISP Copper.net! And the customer support people are awesome for non-techies like me!

You can use the supplied modem directly with a PC to send FAXES just like you can with any other Fax modem. But the router would not be used in that case.

Jenny, "most" is not "all" and the dial-up routers are quite obviously for those of us who DON'T have fibre optic broadband or any access to it.
