Do you have a zyxel series p600, 660R-D1 dsl modem user manual? I have one and have a range of kbps of 3050 to 240 kblps. I thought I would read and see what to expect, Earthlink and the phone company blame the other for the failure to maintain connection and dsl speeds. thanks

The user manual or user guide of the 660R-D1 is available on the zyxel.com site, if you go into the following path:
Support and downloads --> download library ---> up at the right hand side top you see a drop down menu with list of products, choose 660R Compact series. This brings you to the download page and you can choose out
Model :
P-660R-D1
Version : 3.40
Language : English
OS : N/A
Release Date : 07-14-2006
Size : 7 MB

Citating the part from the manual that I think is important (see down at the bottom of this post the speeds, and the note that it may be influenced by your ISP standard. Ask your ISP what they use.):

1.1

The ZyXEL Device is an ADSL2+ gateway that allows super-fast internet access over analog (POTS) or digital (ISDN) telephone lines (depending on your model).
In the ZyXEL Device product name, "R" denotes an integrated router and "D" denotes a chip set standard.
Your ZyXEL Device product name ends with a number. Models ending in "1", for example P660R-D1, a denote a device that works over the analog telephone system, POTS (plain old telephone service). Models ending in "3" denote a device that works over ISDN (Integrated Services Digital Network). Models ending in "7" denote a device that works over T-ISDN (UR-2)

1.2

The DSL RJ-11 (ADSL over POTS models) or RJ-45 (ADSL over ISDN models) connects to your ADSL-enabled telephone line. The ZyXEL Device is compatible with the ADSL/ADSL2/ADSL2+ standards. Maximum data rates attainable for each standard are shown in the next table:

ADSL:
Up: 832 kbps Down: 8Mbps
ADSL2:
Up: 3,5Mpbs Down: 12Mpbs
ADSL2+:
Up: 3,5Mbps Down: 24Mbps

Note: if your ZyXEL Device does not support Annex M, the max ADSL2/2+ upstream data rate is 1,2Mbps.
ZyXEL Devices which work over ISDN do not support Annex M. The standard your ISP supports determines the maximum upstream and downstream speeds attainable. Actual speeds attained also depend on the distance from your ISP, line quality etc.


Please let me know if the above answered your question:)

Tip

My Internet connection so slow?


<p>The type of Internet connection you use is the most important factor in determining your connection speed. The three most common ways to connect to the Internet from home are dial-up, DSL, and cable. If you have a choice, cable is usually the fastest, but both DSL and cable are faster than dial-up. <br /> <p>Many Internet providers also offer Fiber Optic Service (FiOS), which connects to the Internet using light over an optical network. In your home, you still connect your computer through copper wiring. The advantage of FiOS is that it can provide higher speeds than traditional copper wire connections such as DSL or cable. Some Internet providers offer multiple options, depending on the area you are in. More populated areas are more likely to have FiOS available. Check with your phone company or Internet provider for more information.<br /> <p>If you use a dial-up connection, there are a couple of good ways to optimize your Internet speed. First, use the fastest modem you can. The fastest modem you can use will send and receive information at a rate of 56 kilobits per second (Kbps). You won't get a full 56 Kbps speed most of the time, but with a good phone line, you should approach at least 45-50 Kbps. <br /> <p>Second, make sure that your phone line is in good condition. If the telephone wiring in your home or business is old or deteriorating, you might be picking up stray signals or cross talk from other phone lines. These problems will slow your Internet connection because the modem will have to send the same information over and over until it's transmitted without interruption. Check your telephone wires to be sure they aren't damaged, frayed, or twisted around power or other telephone cables. If you notice crackling in your phones, you might want to contact your phone provider to have them check the lines inside and outside your home to make sure they are in good condition.<br />

I have just recieved a toshiba L20 - 197. it was a present of a friend so i do not have the user manual. i was told that it has wireless internet but i cant seem to connect. does it require a modem or any...


Wireless communication This model has three ways of connecting:
- wireless lan (from a wireless router or Wi-fi)
- wired ethernet (connects to dsl or cable modem via network cable)
-wired 56K modem (connects from phone jack to wall jack-slowest)




Compliancy : Wi-Fi® <----------
Network Support : 802.11b/g integrated
Wireless Technology : Wireless LAN
Wired communication topology : Ethernet LAN <--------
speed : 10/100 Base-TX
topology : international V.90 modem (V.92 ready) <------
speed : 56 Kbps data and V.92 data fax
Regardless of how you connect, you must first have a Internet Service Provider.
If you don't already have one, look in your LOCAL phone book under "internet", call a few and find out what they have to offer. If your just surfing the net, reading e-mails, etc. a 1.2m connection will suffice.
If your gaming, hosting a web site , or performing any other bandwidth consuming activity you might consider a faster connection.
The price per month is also a factor.
i usually take a few notes on price, availability in my area, speeds offered, features offered and wether they give me a free modem with thier service.
dont do 56K dial-up, you will beat yourself silly while you wait for the webpages to load.

My computer keeps telling me I do not have an internet connection when I connect my router. I can unplugg the router and plug it back into my dsl modem and the internet again works. why won't my router...


More info would be helpful, but I am assuming that you have a router device that is not the DSL Modem, maybe a linksys, or something? Most likely what is happening is that the DSL modem is assigning private IP addresses, like 192.168.1.x, and the router is obtaining that IP address on its WAN interface, but is also configured for the LAN at 192.168.1.x, which is the same subnet, so it cannot route packets to the internet properly, as both interfaces have the same network range. Can you give me more info? I can try to walk you thru step by step.
Step 1. Verify current IP address when internet connection is working. (Go to a command prompt and type ipconfig, press enter, and document what your IP address is, also document the gateway address and subnet mask)
Step 2. Connect to the router instead of the DSL modem, do the same thing, document your IP address, gateway, and subnet mask
Step 3. Compare the two, your IP may be different, and the gateway may even be different, but see if both are trying to use the same IP range.

If they are the same, or close (the first 3 octets(set of numbers) are the same) then you will need to configure the lan side of either your DSL modem, or the router to be on a different IP address.

To do this will vary depending on the model of your router, so if you respond in the next few hours, I will still be online, and will try to assist.
