| Question about ping and tracert results I'm experiencing intermittent internet connectivity that seems to go away (for a few hours at least) when I reboot my modem.
I'm not sure if the following is diagnostic or would help to identify the problem:
When my internet connectivity is fine, and if I ping 4.2.2.2 (what I use for a hard-coded DNS server), I get 0% packet loss, and good ping times (under 25 ms). If I do tracert to 4.2.2.2, my first "hop" is to my modem / gateway (192.168.2.1), then about 5 other hops (each listing 3 times, an ip address and rDNS), and the final entry (4.2.2.2).
When my internet connectivity becomes flaky or seemingly dead, I can still ping 4.2.2.2 with good results, but a tracert to 4.2.2.2 shows about 10 intermediate hops between 192.168.2.1 and 4.2.2.2. All 10 intermediate hops show 3 "*" for the time and "request timed out" on each line. The last line can show 0, 1 or 2 "*" along with 3, 2 or 1 times and then the resolved rDNS for 4.2.2.2.
So my question is - is this a "routing" problem? A problem with "routing tables"? Is it a problem with how I've configured my DSL modem? Or is the problem totally on my ISP's end?
I know that this isin't a PPPOE issue, but I'm not sure where else on dslreports I could post this question. | |

1 edit | Re: Question about ping and tracert results And you say that the issue is resolved immediately after rebooting your modem?
If so, I would first try replacing your modem. Borrow one from a friend or work if you can, and at least try to determine if it is or isnt your modem causing the issue.
If the problem does not resurface after swapping modems, I would look at replacing it permanently, and throw your old one in the bin, or leave it in the cupboard as a backup incase your other one fails.
If the issue persists with a different modem in place, it will be time to call your ISP to report a fault.
Try to get a completely different brand of modem, just to make sure it is not firmware/hardware related. Even though some modem manufacturers use the same hardware, software/firmware can be extremely different between them, and sometimes it makes all the difference. | |
