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
Earthlink www.earthlink.net
Netscape Internet Service  www.getnetscape.com

PeoplePC www.peoplepc.com
BellSouth www.bellsouth.com

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.

Dial up connections are very slow and useful only for retrieving email, sending messages, and web-surfing on simple sites. Amazon TV/Apple TV and other such devices require a high speed broadband connection. Would not recommend the GAC-252 for this.

I want to buy this as I have dial up only and many device like iPads,Amazon tv Apple TV cameras so on and so on,will this work for me?i will have frontier as my phone service and was thinking of using EarthLink

will this ever be in stock? A lot of people still have dial up as high speed internet is unavailable in 2-4% of North America.

AOL access requires special client software for a PC or Mac. So it can't be supported on the GAC

Do you offer or know of a wifi router that can use aol? I don't know why aol won't work with your GAC-252. but I'm confident you know that it will not. Is there a difference in the signal, a disconnect problem or more complicated than that?
By the way, it was not clear what to do in the box below - I figured out but a label would be helpful

I want to apologize for a nasty post on May 7, 2014. Great Arbor refunded my purchase price for the GAC-252, which I was unable to use. It turns out as of as late as today, I finally was able to acquire reliable internet connection. Turns out the phone company had me connected to a bad line, and finally repaired it today. It took 5 visits from them to finally get this resolved! I think that the GAC-252 was likely a good unit, but could not be used under those conditions. Great Arbor refunded me, and I thank them for the professionalism through the frustrating weeks we both tried to resolve the situation. Thanks again GAC!

Tried our best to help the customer but could not solve the issue of why it did not work with his ISP. Offered a full refund even though the customer wanted an exchange because it was clear that there was no hardware or software issue with the router. Not much else we could do. Easy to call something a piece of junk - but there are plenty of users out there who love this unit - the only one of its kind available in the market. Software developed and supported completely in the USA.

Box of junk. Never worked from day one through day three of constant contact with tech support. Told it was my fault at the end of the fiasco. General HAM operator, BSEET degree, AA degree. Military telecommunications tech before college. Circuit board designer for two OEMs. Technical sales and purchasing for Tyco Electronmics. Just the average dummy, who couldn't figure it out with "Great" Arbor's help. Surely, they'll leave one on their website to balanced and fair.
