DNS Timeout

12 New Member
Hi everyone,
I live in rural France and at long last have accesss via WiFi to ADSl. Only problem it cuts out about every 30 minutes. A ping test to IP shows no problem but to the DNS primary, initially 70ms then gradually increases to 120, 200, etc until 'timeout'. It then remains offline for about 3 minutes. Our supplier seems either reluctant to address the problem or incapable. Does anyone have any ideas what might be the problem?
Thanks in anticipation,

I'm always on the right line unless I'm off line occasionally ;-) The OP mentioned 1.86 miles which is quite a large distance. Normal antennas only operate well within a distance of 80 ft or so (in the line of sight). I'm tempted to suggest a parabolic dish antenna or even a Yagis antenna. Those little stick antennas just don't make it over distances like that.

BTW I was talking about 4GHz, that should be 2.4GHz of course.

kind regards,

That may prove to be helpful info, but I really need answers to my questions in post #7 (quoted) to be able to consider the problem clearly.

I have an office pc and a laptop connected to a d-link ethernet switch. In turn this is directly connected to the antenna fixed on the wall and pointed directly at the antenna at 1.69 miles. From there the signal is transmitted about 4.5 miles to a large radio transmitter and the signal forwarded on to the town of Aurillac. Other users go via a different antenna to the radio transmitter and don't appear to have the same problems. It would appear that the problem lies within the control system associated with our local antenna that serves about 20 customers.
Hope this info helps you,

So none of your equipment uses wireless technology to connect with your local D-Link ethernet switch?

Please also provide any IP addresses that you have. Internal & external for the switch if possible.

No, both are by cable. PC I.P. Laptop I.P.
Default passerelle Staic I.P. used as Meshnet does not accept dynamic I.P.s

It seems like the only WiFi involved is your link to your provider, via equipment entirely configured by them. Everything on your internal network is wired.

I see nothing here that could be the problem other than the service provided for you. I would think they would need to run some diagnostics themselves to discover the issue if they were interested enough.

You could try using TraceRt to your DNS server when it's running ok, and again when it's not, to compare the two. Unfortunately I doubt that would help much until you could convince your proviser to look into it for you.

Thanks for your efforts. I've tried TRACEROUTE from numion .com and not once has it managed to complete the trace. It always stops one step from home. Meshnet have said they are looking at the EDF electricity supply! I cannot imagine how any fluctuations can have the observed effect. We'll wait and see.

Sometimes the rate at which the electricity pulses (50 Hz etc) can have an adverse effect on wave energy transmissions (WiFi). Alternatively the reliability of the supply may be an issue. I'm guessing of course, but there are often technical issues we wouldn't anticipate unless we had the relevant experience.

Apparently they are going tocheck the supply this week. Personally I can't imagine that even if it is pulsing it would create the observed problems. I'll keep you informed.
Have a nice day,

I am having a time out issue when multiple users are accessing the server. This time out does not happen all of the time. My understanding is that the time out value is actually set in two places.

I have already looked at the time out setting in IIS, and it...
