How many devices can Netgear DSL Gateway Model 7550 hold?

My family recently got the Netgear DSL Gateway Model 7550 from ATT and I would like to know how many devices can be connected to it. As of right now we have about 18 devices. 4 Iphone, 2 printers, and 12 computers. I recently just bought the new Lenovo Yoga ultra book with windows 8. And I have had some problems staying connected to the Wi-Fi. I would connect to the Wi-Fi, then shut downnm Lenovo yoga and then I would get back on my computer and I would be kicked out of my Wi-Fi. Can anyone explain why this is happening and how many devices my Netgear DSL Gateway Model 7550 can carry?

Most of the time you won't have problems until you reach 25 or more Wi-Fi clients, this would not include Ethernet clients.

Wireless signals are affected by many factors including distance, wall density, electrical interference, directional antenna range, etc.

All of these factors will affect your actual wireless range. As wireless connection quality varies the connection speeds are renegotiated. The WLAN connection may start at 150 Mbps and end up at less than 10 Mbps or drop entirely.

Just because a particular wireless router or device works good at one location does not guarantee that it will have similar performance in a different location due to variance in the factors listed above.

You should try to centrally locate your wireless router or gateway up high and away from dense walls and electrical and 2.4 GHz wireless interference such as microwave ovens, cordless phones, baby monitors, etc.

That being said,

How fast is your DSL Internet connection? Http://speedtest.net

DSL is among the slowest of the mainstream broadband types. Cable or fiber optic is generally much faster.

Your Internet speed is determined by your ISP and is measured in Mbps (Millions of bits per second). You can test your Internet speed here: http://speedtest.net/...edtest.net" class='ext_link'>Http://speedtest.net/...edtest.net

For example if you pay for a 3 Mbps Internet connection, you will get 3 Mbps.

No router or connection settings will change your 3 Mbps Internet speed. This connection bandwidth is shared among all of the users of your LAN. So any bandwidth others are using will be deducted from the total WAN (Internet) bandwidth that is available to you.

If you have a 3 Mbps Internet connection and one user is utilizing 2.5 Mbps of the bandwidth to stream a Netflix movie that only leaves 0.5 Mbps for all of the rest of the users on the LAN.

In simple terms, the more users you have the more speed will be required. Streaming video, such as Netflix and Hulu require a lot of bandwidth. Here are the minimum recommendations from Netflix.https://support.netflix.com/en/node/306

The only real way to speed up your Internet connection is to get a faster ISP or speed tier.
