Hello! I'm so sorry about long question but I really REALLY need help. This problem drives me crazy ever since 2 years ago and such.

So I had a Netgear WPN614 before. It really worked fine until about a year after I used, I started to have unstable internet connection problem. So basically, my internet randomly became disconnected then shortly after, it came back. I reset the Router into Factory default and even changed channel and such but nothing helped. After working fine for a day, the router started to have unstable problem again. So I bought a new router, Netgear WPN824.

Same as the previous story, it really worked fine until a year after, it started to have same problem again. Someone told me that the power supply might be worn out or something but nope, I checked it and it seems fine. I changed my network channel into different one (1-11), factory-default reset, upgrade the firmware and everything but nothing helped.

I really feel like my router started to become weird about a year after I use and I really am not sure what's wrong. Is it my computer? I checked spyware thing but nothing is detected.

Another thing I found out is that if I directly connect modem and computer through ethernet cable (so nothing involves router) then it really works fine, no unstable problem and such. But when I connect it through the router, when the internet disconnected, the modem is starting again. What I am saying is that the unstable problem also cause modem to loose connection for awhile.

So could anyone please helps me what should I do? Do you think the unstable is because of my computer or router? The unstable problem seems getting worse recently. (So it gets disconnected more often)

Thank you so much!
Sincerely,

What brand modem do you have? Who is the ISP?

Thanks for answering my question.
So I'm currently using Cable Modem as Linksys BEFCMU10 and the ISP I'm using is Cox. Oh and in case, my router is Netgear WPN824v3

Thank you so much again!

I searched Google & apparently you're not the only person to have that disconnection problem.

There is a web interface with that modem. There maybe some settings that will correct the problem.

To open it, connect your PC directly to the modem & open the browser. In the url box, type http://192.168.100.1 & press enter.

What's not clear to me is if the modem is doing NAT, the router's default IP address may have to be changed to match the modem. Look at page 10 of the pdf file & find the same box in the web interface. What IP address is there?

So I connect my computer and modem directly and I entered 192.168.100.1 page and was able to view the Modem information; however, the page shows me with different layout that the pdf file you gave me. (Something likehttp://eqrunner.com/CrewNotes/CNfiles/CNCoaxsplitter-Linksys.jpg). I could see my Cable Modem MAC Address but not IP in that page. :( Perhaps I can try out using "ipconfig" command? If so, which IP address do you need?

Also, I found out in Modem's log page that whenever I had the unstable problem, the log says something like this:
- SYNC Timing Synchronization failure - Failed to receive MAC SYNC frame within time-out period
- Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 timeout
- No Ranging Response received - T3 time-out
- DHCP WARNING - Non-critical field invalid in response.

I'm not sure if this is related though.
Anyway, thank you so much again!

I searched some of those error messages. Some people say that it's a bad splitter, some say it's the ISP's problem & you should call them. Since you said that everything works fine with a direct connection to the modem, I am assuming that it's not on the ISP's end. However, that maybe a mistake on my part.

Before you call them, fun ipconfig /all twice, when the PC is connected to the router & when it's connected directly to the modem. Post both outputs.

Thank you so much for all the answers!
Now that I connect my computer through Modem, it seems to have same unstable problem so I think that you're correct, it's ISP's fault. I did that before (connect through Modem) and didn't happen but now, it seems to happen the same problem. At the same time, I am not so sure if it's from my computer's fault. Whenever I go onto Internet Browser, like Firefox, all the sudden, the internet drop and loose connection then comes back. I am not sure if this is possible though, like if you go to IE or Firefox then it makes your connection loose; otherwise, it is fine.

Thank you so much for the answer again!

Call the ISP. Tell them that even with a direct connection, you have trouble.

Also, it can't hurt to look for loose connections in the coaxial cable, inside & outside the house.

Thanks, guapo for all the answers!
I just called COX and they said it's the splitter, either the one inside my apt or outside of my apt.
I didn't know that splitter could affect the unstable connection.
Thank you so much again!

Sincerely,
