so my network has been going down almost everyday. just started a week ago. idk wats failing ether modem or router. how would i go about figuring out witch on it is? i have to power cycle to connect again. and sometimes when i shut off pc and turn it back on thats when network goes down. i have like 5 things conneted on my network.

ISP---------------***

modem--------D-link DCM-202 - http://support.dlink.com/products/vi...ductid=DCM-202

router-----------D-Link DGL-4100 - - http://www.newegg.com/Product/Produc...82E16833127060

 

a network is when you have one or more host computers linked to multiple other systems (computers). If my living room pc were sharing the same router as a computer in my bedroom it would be considered a "network".

Are you just wondering what the deal is with your one system or are you actually on a network?

The only reason i ask is because it will vary for what kind of solution you might need.

 

could be your ISP or your router. I would call your ISP and get them to check it out.

 

Take the router out of the circuit and use an ethernet wire from the modem to a computer, laptop whatever. This will determine if it's the router causing the problem. Of course you can only use one computer this way but it will determine if it's the router or modem.

 

I was having the exact same issue with my netgear router and found out that the router was overheating and would cause that issue, I am too lazy to google to see if that dlink has a similar issue, but I would definitely look at buying a new router.

 

I'm a computer tech. Try this:

Next time this happens go to Start, Run... Then type in When the black box comes up type in You should get something like this. Now what you're looking for is the "Default Gateway." Mine is 192.168.0.1. So what you need to do to make sure your router is working correctly is in that same window type in (using the address that you found out) This will "ping" the router to make sure it is still alive. If is really locking up you will get something like If it does respond then it isn't the router. It's probably either the modem or the *** service it's self. Either one, I would call *** and tell them to fix it. Hope this helps.

 

wat im calling my network is my
modem +
router +
pc,tivo,ps3,phone, print server, and pc#2

internet goes down and nothing can go online. i cant even call phone down since its on internet
----------------------------------------------

so it might overheat? huh. i hope not router 100 bucks. i think i got warranty i dnt member tho.
-----------------------------------------------

well i just type the ip of router in browser and log into router setup **** in all u know? i did it when it was down and i could still log in and change stuff.




thanks for all help

 

Ok, then it's definitely your modem or the *** service. Tell them to fix it!

 

This sounds like the modem but you can't be sure until you've done a process of elimination. I have seen where modems are bad and only provide intermintent service. I would also do in your troubleshooting. When you loose the connection, check your ip address. If you have a 192.168.1.xxx, you are still connected to the router (unless you have assigned static ips). Then try and log into the router. If you can not connect into the router, then your issue is with the router. If you can connect, then your issue is with the modem.

 

Everyone's responses are correct, here's a good nontechnical walkthrough:

When your internet goes down, check your modem lights. You should see solid POWER, CABLE and STATUS lights. If this is not the case, call ***, and let them know your modem keeps losing the signal.

If all these lights are OK disconnect the cable that goes from the modem to the router, and plug it straight into your PC, and reboot the PC. If it works, stay like this long enough to confirm you're no longer dropping. If it works, then drops again, call ***. If it stays working, then the prob is your router:

Perform a hard reset on your router (check the manual, usually you just have to hold in a reset button. This will restore all factory default settings. Reconnect everything like you normally have it, and reboot the PC. If it works, see how long before it drops. If it still drops, then you your problem is either the router (plausible), cables (kindof rare), or port on your PC (very rare). I'd swap the cables, as that's easy to do. If the cables dont help, get another computer on the router to see if it still happens. Maybe a friend with a laptop? If they never have any problems, then the problem is your computer. It could either be Windows flaking out (happens to many people if they do heavy P2P downloading, as with Bit Torrent), so wiping the drive and reinstalling windows should help (or lower your bit torrent (etc) settings, or you honestly have a bad port, and should replace it.

This pretty much covers all the bases with the least amount of variables, and the most hardware verification. Please let us know how it goes!
