I would love to solve the problem - but there is not one thing to go on. I don't even know where that log is.. Is that from his modem/router is that something he created on his machine? What? I have never seen such a log to even take a guess to where its from.
What is the make of his modem/router? The device from his isp.. Is his computer directly connected to this device? Does he loose his local IP to the modem/router or just the actual internet connection from the isp device, etc. etc..
This is why I suggest he call his isp.. From the lack of info given there is nothing to be done on this end.
Anything everything you need BudMan, I will try to answer to the best of my knowledge.
This log is generated by a chat program. By accident I learnt that when I am in this chat room, if net goes down, it gives me the message server off Line. After posting yesterday, net worked fine most of the day but then last night around 01:10 AM it started again & since I left that chat program run all night, it generated another Log. I am attaching it.
Modem make & Model : ZTE, ZXDSL 531B ( Made in China ) Provided by Phone company. It is about 6 years old now.
Phone line goes into Modem & Modem is directly connected to computer. They gave me a splitter so I can use Phone as well as net but then I thought the splitter might be causing this so I removed the splitter. So now phone line to Modem & Modem directly connected to computer.
Your question " Does he loose his local IP to the modem/router or just the actual internet connection from the isp device, etc. etc.." is tough to answer but I have started monitoring it.
Here it is :
Modem has 3 lights. (1) Red is Power & stays on all the time (2) Yellow light is DSL & goes down when net goes down (3) Green is Internet. which keeps blinking when net is working & goes down when net goes down. First I observed that when net goes down power light stays on so power is not the problem. Also it takes few seconds for chat to show if net is down in other words I noticed that net goes down & Yellow DSL Light goes down as well as Green Internet light goes down then few seconds later I see a in Chat Log that net is down.
Frequency is totally random. It worked fine till 01:00 AM after I posted this post & then all night from 01:00 AM to 09:00 AM it goes down every few minutes.
I don't know how to attach Log files to this reply which will show you what went on all night. Can you tell me how so I can give you more logs ?
This problem comes & goes for last year or so and I have called my ISP several times & they came out & checked at teir end & couple of times replaced the wiring coming to my PC. Sometimes problem goes away & other times don't.
I have a question. Could it be NIC ? It is Dell T-7500 workstation & under warranty & has built in NIC, right ? So if that is the case, can you or Dell Identify that NIC is the problem ?
Does this help ?
