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 (126.96.36.199): 56 data bytes 64 bytes from 188.8.131.52: icmp_seq=0 ttl=51 time=16.792 ms (...snip...)
3 minutes later, nothing changed:
PING google.com (184.108.40.206): 32 data bytes 32 bytes from 220.127.116.11: 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...
