Hi guys,
I'm having a bit of a problem with my 4mbit ADSL line. On average I get about 5% packet loss as confirmed by pingtest (http://www.pingtest.net/result/13950398.png) and by manual pinging.
I've logged multiple tickets with Telkom to investigate it but I never get anywhere with them. So, I've done some investigation of my own and this is what I've come up with:
1. The problem is not in the wiring of my house. (I crawled around in the roof and managed to place the router on the line that comes in from the pole outside. This did not solve the problem)
2. The problem is independent of any service providers. I've tried Telkom, WA and Afrihost
3. The problem is independent of the router. I've tried various.
4. The problem seems to be located between my router and my router's gateway. Confirmed this by pinging and reverse pinging to various hops in my traceroute.
5. A friend of mine who lives in my neighborhood seems to be having the same problem.
6. Correct me if I'm wrong but I think my line attenuation is ok: (down 52db, up 25.5db)
7. My line's noise margin is 9.3db down and 12.0db up. This is ok too right?
8. The problem does not go away if my line speed gets dropped to 384kb/s
9. My downstream traffic seems to be unaffected (I get 400+ KB/s easily) but my upstream traffic is slow as hell (2KB/s). This is killer on sending attachments with email.
10. Time of day does not matter. There is packet loss 24/7
11. I think my ICMP packets get lost on the upstream, not downstream but that's just an assumption.
From my investigation I'm pretty sure there's something wrong at my exchange but I'm just not knowledgeable enough to be able to tell the Telkom reps what to look for. I've tried explaining everything to them but I'm met with telephonic blank stares. (I've been told to try change my DNS server though, because, you know, that's gotta be the problem :erm
Anyone know what magic phrases I can tell the Telkom reps so that they'll know what the issue is?
