For some reason I cannot get internet by directly connecting my ethernet from my modem to my computer so I have to do it though a router. The problem with this is that my router has problems running internet on some Valve games so I need to be able to directly connect to the modem. Can anyone help figure out why I am not getting internet from my modem when i directly connect it?

Try restarting the the whole system.
Turn off the computer and unplug the modem. Pause for about a minute and plug in the modem only, giving it a minute to boot. Now start the computer while it is connected to the modem and it should get you on the internet.
The reason your router gives you problems with online games is because the games require two way communication that is being blocked by the router. You should be able to find out what ports you need for the game in it's documentation and set the router up to forward the ports to the computer.

What kind of modem? I won't assume that its a Arris TM402P. I would need make and model. Also be aware that drivers are only required if you are connecting to the USB connection on the modem. The USB connection is generally unstable and always slower then the ethernet connection. The ethernet connection does not require a driver for the modem.

I have the same modem but a different problem. Sometimes the two telephone lights start blinking slowly, and then my internet slows to unusual speeds. My cable company came out yesterday and *fixed* the lines but it seems to be running slower, with more downtime... Could this be a modem problem, or is it a signal problem?

I would suggest doing a full reset of the modem. If you can, reset the modem to it's factory default settings and then shutdown your entire network. Then go through the steps in the following link.

It sounds like you either have a failing modem or your ISP's config file is corrupt or not compatible with your modem or you have someone trying to use your account with a cloned modem with your MAC address.
If your modem is leased from your ISP, trade it in. If not, you may need to purchase a new modem but check with your ISP for compatibility before making the purchase. If someone is using a cloned modem with you MAC address, replacing the modem will solve the problem.

Hi
I have ARRIS Cable and I have problems with IE7. I did typing http://192.168.0.1 and http://192.168.1.1 or http://192.168.2.1 all not working cuz it sayin Internet Explorer cannot display the webpage
Most likely causes:
You are not connected to the Internet.
The website is encountering problems.
There might be a typing error in the address.
I need your help please?

Actually you have Comcast Cable with perhaps an Arris Cable Modem but I don't understand at all what your asking.
Why do you think IE7 is the problem? Did your internet quit working when you upgraded to IE7? Did it work and then just stop? Has it ever worked with your cable internet?
Why are you typing the three addresses you quoted? If their not HTTP servers on your local network with web pages on them, that is the message you should receive. These addresses are the default addresses for various routers but if you don't have them, they won't be available through IE7. Their also all on different subnets so it's unlikely that all three would be available anyway.
Do you have a Router connected between your computer and the modem? If not, are you connected to the modem by USB or cat5?

I have a problem with the standby function on my arris T402 modem. I have internet through Cox, and the internet at Cox were down for about 3 weeks over the holidays, and when they fix it, now my modem will not go to the standby mode. I press the button, but the modem stay full connected. Could this be a Cox problem, or is it a modem problem

I'm not to sure with the Arris Modem but you may be able to access it ( Maybe http://192.168.100.1 ) and set it to it's defaults and then restart the entire network as described in the following thread.

as long as your modem is registered with an isp you should be able to connect to the internet with it.
you should have the cable wire connected to the modem , then ethernet or usb going to your pc. shut down your pc, then reboot your cable modem. it should have a small button somewhere on it , usually in the back. give it a couple of minutes to boot up. then reboot your pc. once its up try to connect to the internet with your browser. does this work?
we need more info for your home network. are you connecting multiple computers? do you need those computers to communicate with each other or just have access to the internet?
if either is the case, then you may need a router or wireless router.

this is the user guide for your modem. you may want to check your network settings. you can verify them by going to page 31 in this manual and clicking on your operating system.

You do not need a router to connect 1 PC to the web through a cable modem butyou do need a router or some kind of hub or switch to connect multiple PCs tothe web through a cable modem.
In most cases, depending on the ISP, you will need to restart the cable modem any time you connect a new device to it. Some systems will store the Mac address of the last device connected to the modem and will not allow a new device to connect until the cable modem is rebooted. Rebooting the modem clears the mac address out of the router on the ISPs end.

Actually with most cable interntet providers you cannot use a hub or switch unless you purchase additional ip addresses.

Some Modems have a DHCP server and router built-in. With these, all you need is a hub or switch. If the modem does not have the router/DHCP server built-in you need a router.

exactly, most of the time the cable provider will not issue these unless the customer has purchased home networking at the same time as the internet service. However, the customer can, in most cases, buy a supported after market modem/router combo and have it provisioned at no expense by the ISP. This would be in place of their stand alone modem as most companies will not provision 2 modems to the same account as it creates a billing problem.

Before anyone rushes out and buys a modem with the router inside, consider that you are sacrificing some control of your router to the discretion of your ISP. In some of these modem/routers you can't even setup port forwarding.
A separate router provides the best control and security for you the customer.

Arris 502 with router work arounds.
The problem you are having, is the modem assigns 1 ip address to your home. If you want to connect directly to the modem, you will need to reset the computers ip address, and restart the modem. This is for ppl like me who are using a router with an arris 502 modem that want to hook up multiple computers.
Disconnect all networking lines.
Hold reset button on back of router until it blinks (indicates reset)
Unplug router.
Plug network cable from modem into WAN on router
Reset Modem
Plug power back in on router
plug network cables into router from computers
turn on computers
You now can use the internet on both computers.

The steps you posted aren't "work arounds", They are the required steps needed when the first device connected to the modem is changed.
When someone decides to go from a single computer directly connected to the modem, any cable modem without a router built in, to a network with multiple computers connecting to the modem, a complete restart of the network including the modem and router are required. Then the modem MUST be started first and allowed to boot, the router MUST be started next, then you can start your computers. If you go buy a new router, you would need to do this startup procedure again. When you add computers to the network, you don't need to do this restart. It is only required when you change the first device connected to the modem, in this case going from a computer to a router.

Your router is being hit with constant normal mode and common mode noise from the utility power. It interferes with communications, causes unexplained resets, and is impossible to clean up without installing a low impedence isolation transformer. Your routers micro processors are losing their ground reference as these transients flow through your home electrical system. Regular surge protectors DO NOT fix this problem! Most actually make matters worse. Get a Powervar ABC065-11 and plug your cable router in to it. Your lockups, resets and other weird problems you cable company can't fix will disappear. Keep the conditioner at cords legnth away from you wireless modem to prevent the tranformers magnetic field from interfering with the wireless signal. Get an ABC100-11 and plug both your Cable Router and wireless modem in to it. You'll notice the service quality improvement right away. Oh, by the way,.... your PC is in plugged into the same dirty power. Have to restart, reload, defrag, is your system running slow? Put a Powervar on it and clean your hard drive once. Most problems will go away. What's left you'll be able to fix, and they will tend to stay fixed.

The information in the above post borders on a sales pitch for a specific product line which is against the Cable-Modem.net Terms of Use policy but some of the post is relevant to the thread which would allow some to benefit from it so we're going to leave it.
To anyone reading this post, ANY good quality power conditioner properly rated for the intended purpose will do the job. They are available from companies like Tripp Lite, APC and many others as well as the brand mentioned in the above post.

Welcome to the forum.
Fresh ideas are always welcome and the possibility of power issues is definitely relevant to this thread. We appreciate your bring this information to the forum.
While I agree that power fluctuations and noise can be a problem especially in densely populated areas where you share a transformer with your neighbors, I have a problem with a few of your statements:
"Regular surge protectors" of course are not power conditioners but simply surge protectors. They're not intended to condition or regulate the power but they will NOT make the problem worse unless they are defective or not properly grounded.
You said, "Get a Powervar ABC065-11 and plug your cable router in to it. Your lockups, resets and other weird problems you cable company can't fix will disappear." No one could make such a guarantee. I would agree that in many cases a power conditioner is a benefit but definitely not the single cure all and not generally very cost effective. There are many issues that can cause the problems discussed in this thread. Things like too many splitters before the modem, an open connection on a cable or splitter along the coax to the modem, radio interference from many different sources and a defective coax or modem just to name a very few.
I'm sure your knowledgeable in the area of power conditioning but a majority of the people that frequent this forum have a limited knowledge of electronics. I'm not saying their unintelligent, just that electronics is not their area of expertise. They come here because they don't know what their problem is and would like someone to help them in a way thats easy to understand. Many of these people would find your first three sentences to be jiberish. It's generally better to explain things in a simpler fashion.
The "low impedence isolation transformer" that your referring to is simply a power conditioner.
Wikipedia Definition: A power conditioner (also known as a line conditioner or power line conditioner) is a device intended to improve the "quality" of the power that is delivered to electrical load equipment. While there is no official definition of a power conditioner, the term most often refers to a device that acts in one or more ways to deliver a voltage of the proper level and characteristics to enable load equipment to function properly. In some usages, "power conditioner" refers to a voltage regulator with at least one other function to improve power quality (e.g. noise suppression, transient impulse protection, etc.).
The terms "power conditioning" and "power conditioner" are misnomers, however they have been accepted in common usage to convey an image to those not intimately familiar with electrical theory. It is voltage rather than electric power that is being acted upon, and "conditioning" is actually the control and adjustment of voltage.
Power conditioners can vary greatly in specific functionality and size, with both parameters generally determined by the application. Some power conditioners provide only minimal voltage regulation while others provide protection from half a dozen or more power quality problems. Units may be small enough to mount on a printed circuit board or big enough to protect a large factory.
Small power conditioners are rated in volt-amps (VA) while larger units are rated in kilo-volt-amps (kVA). While no single power conditioner can correct all power quality problems, many can correct a variety of them.
It is common to find audio power conditioners that only include an electronic filter and a surge protector with no voltage regulating capability.
End Wikipedia definition
A power conditioner could be a benefit but is it worth the $400 - $600 that your recommending? To some maybe but many others aren't having such problems so the expenditure would offer little to no gain.
In most cases here in the US, if you suspect that your having power problems, call your power company and they can do a test that will log the power characteristics to your building over a given period of time and if there are some serious problems, they may provide a power conditioner or line conditioner or replace the transformer if it's the problem.
Also you said "Oh, by the way,.... your PC is in plugged into the same dirty power. Have to restart, reload, defrag, is your system running slow? Put a Powervar on it and clean your hard drive once. Most problems will go away." The only part of this statement that I might agree with is that your computer is running on the same POSSIBLY dirty power but that's irrelevant because the computers internal power supply is a power conditioner. It takes the input power and very accurately produces clean + & - 5 volts and + & - 12 volts for the internal components. As far as a machine locking up or needing to be defraged or being slow, these could not be related to power issues unless the power issues are very severe. A machine that locks up could be anything from bad capacitors on the mainboard to bad memory or a failing hard drive to mention a few. A system thats slow can be caused by anything from needing to be defraged to having too many TSR's running or viruses or just poor configuration +++. As far as defraging the hard drive goes, that is something that always needs to be done and has nothing at all to do with power. Every time you open a read/write file on the computer, the computer creates a temp copy of the file, then when you make a change and save it, the computer writes the new changed file to a new location and records that location in the File Allocation Table before it deletes the old file so where the old file was, there is now an empty sector or series of sectors. The next time the computer writes a file to the HD it may write to that series of sectors but if the file is too large to fit in that single spot it will write part of it there and the rest somewhere else on the drive creating a fragmented file. Thats how hard drives work so defraging is always necessary regardless of how clean or dirty the power is.
