Hi,

Not strictly linux but...my internet signal has been experiencing problems for a while now. It is hard to nail down exactly the problem but the signal seems to fluctuate – sometimes it takes 10-20s to access a web page (as it happens it took approx 1 minute and a timeout to access LQ). As a speed test came up with the result “line speed 18.52 Mbps, download speed 2.26 MB/s” I think this time is unreasonable. Most times web pages appear immediately which is what I expect.

My signal feeds into an ISP supplied modem, then to a TP-LINK TL-WR841N wifi router, then to a switch. I decided to ping 8.8.8.8 from a F20 PC (connected to the switch) and a Pi (running on wifi). I have attached the results from both PC & wifi. Look at seq # 155 to 175. Does this look reasonable? During this test there was no unusual load on the router.

Interested in opinions on the ping test. Next step is to change the cable from modem to router. Let's see if that makes a difference. If anyone knows a way to extract info from the TL-WR841N I would be grateful.

Cheers

There may be issue with DNS resolution.
What is your Primary and Secondary DNS configuration ? If they are provided by your ISP, Change to 8.8.8.8 and try to access it again.

I changed DNS to 8.8.8.8 on my desktop and, after ifdown/ifup, browsing is a much smoother experience. I will give it a day or 2 before marking this as solved. I will note that the pings are still showing large gaps - maybe this is normal!

I suppose a concern of this action is that I am tying my DNS to Google? Is that right? is there an alternative?

Thanks

Actually, You are using Google's public DNS server. There is no harm to use it. even you can use 4.2.2.2 which is again a public DNS server.

There is OpenDNS and DynDNS if you prefer. Probably more, I haven't looked further. I use OpenDNS myself.
