I have an ADSL connection at home. Pings times are usually acceptable right after rebooting the modem, between 15 and 60ms to google.com. A few minutes later they go up to 900ms or even higher up to 3 to 4 seconds. There is only one phone plug in the house with the ADSL modem connected. Nothing else uses that line. I asked my ISP about this for several times and all they can come up with is the dreaded "did you turn it on and off" response.
Problem: Internet surfing becomes horribly slow, watching video's is out of the question.
Diagnosing: Running ping (with and without -n to bypass DNS lookups) to google.com from the modem.
What I tried:
- changed the ADSL splitter
- bought a new ADSL modem
- changed the ADSL cable between the modem and phone plug
- checked down and upstream rates (modem says 8708 Kbps down and 1037 Kbps up, exactly what my ISP sees)
- changed from my ISP's DNS servers to Google's public DNS servers
A small sample:
PING google.com (74.125.136.101): 56 data bytes
64 bytes from 74.125.136.101: icmp_seq=0 ttl=51 time=16.792 ms
(...snip...)
3 minutes later, nothing changed:
PING google.com (74.125.136.101): 32 data bytes
32 bytes from 74.125.136.101: icmp_seq=0 ttl=52 time=2417.5 ms
(...snip...)
Anybody has some pointers on what I should try next? Changing my ISP is probably one possibility...
1you do not mention if you are using a switch/router. Are you connected directly to the modem? if not, have you tried that? – Logman – 2013-03-02T14:14:50.117
Thanks Logman, it's a modem/router in one. I run the ping tool FROM the modem/router to make sure the problem is not on my internal network. – Cimm – 2013-03-02T14:16:26.200
have you tried reseting modem/router? turn off, unplug everything, hit the reset button on modem/router? Have you tried a different phone jack? or even go to the junction box (where it comes into the house? – Logman – 2013-03-02T15:45:59.797
Logman, it's even a new modem, different hardware, so yes I did reset everything. The different phone jack is an idea but there is only one in the house. Haven't tried the junction box, will try that. – Cimm – 2013-03-02T16:06:03.400
Check your startup programmes. You may find there are a lot of updaters messing up your ping times – Tog – 2013-03-20T13:54:15.117
