Okay. So my internet connection is playing games with me.
At least once or twice a day, it'll stop working. I'll have to unplug everything, let my modem reboot, then let my router reboot, then let my extender reboot. It's annoying.

Here's my setup.
I have a modem, connected to my router. My router has 2 ethernet outs; my computer, and my Sprint Extender.
The router model is a Netgear WNDR3400. Modem is an Arris DG950A.

Any way I can fix this?
 
Unplug the router and switch it to another port on your adapter. Netgear is very common to blow ports on surge protectors.

I forgot to specify, but it's the modem that's giving me problems. I'll get orange lights every so often, and that's when the connection stops working until I reboot everything.
 
You should probably have a tech out if you think it's the modem, could be any number of things.

You said it was Modem > Router > Computer & Extender, how could it be the extender if the modem is what's having issues?

I said I believe it's the modem, but it could be the extender causing the issues.

It could also be your computer or your router, hell if you're going to guess it could be the power supply. As I said, it "could" be a lot of things, if you get a tech out he can test the modem to determine if the problem is either signals, their modem, etc.

They should come out for free (you can ask first), if they determine it's not their problem they'll leave and you've narrowed down what it could be.
 
Since you mentioned you're getting orange signals on your modem every so often I think that something is wrong with incoming signal - that's being said, you should definitely get a tech out.

Just as a possibility though: your wireless router might be set up to automatically determine the operating channel. I noticed with Netgear that these routers act like retards pretty often and once they notice interference with another devices, they attempt to switch the channel automatically.
To prevent it from happening, set up a specific operating channel for a wireless router. In THIS manual on page 24 it says:


4. Set up the 2.4 GHz wireless network:
[-----cut-----]
b. Select the operating channel for the wireless mode. The default is Auto. When Auto is selected, the router finds the best operating channel available. If you notice interference from nearby devices, you can select a different channel. Channels 1, 6, and 11 will not interfere with each other.
[-----cut-----]


Also, try plugging in your PC directly to your modem to see if the issue persists. If it does - the problem is definitely with the modem/incoming signal. If the problem goes away - then it's either router or extender that causes it.
 
He could try looking at his signal levels, I'm not aware of all the ips but I know 192.168.100.1 is common. See if that ip works, then take a screenshot of your signal levels.

For Netgear it's usually 192.168.1.1
Or you are talking about logging in to the modem? For Arris modem the IP is 192.168.100.1. It would be beneficial for sure to see his signal levels.

Which do you think? :suspicious:
 
yeah, the router config page is 192.168.1.1 and the modem levels page is 192.168.100.1.

How do I make sense of this data?
 
Signal to noise ratio looks a little high, but it's probably within the limits. Go with psycho. A tech would be able to tell you for sure. The signal levels wouldn't be the only thing they could test, I still say you should have them out.

Downstream Power:
You generally want between -12db and +12db. Most modems are rated from -15 to +15. Anything less or more than that and you may have quality issues.

Downstream SNR:
This number is best over 30, but you may not have any problems with down to 25. Anything less and you will probably have slow transfers, dropped connections, etc.

Upstream Power:
The lower this number is, the better. If it is above 55, you may want to see if you can reconfigure your splitters. Anything above 57 is not good and should be fixed ASAP. (This is getting pretty close to not being able to connect.)

Upstream SNR:
Anything above 29 is considered good. The higher this number is, the better. If this number is below 25 and 29, you have a minute amount of noise leaking in somewhere. If it's anything less than 25, you want to get it fixed as you may have a lot of packet loss or slow transfer rates.
