Revision history [back]

I'm dealing with a pretty difficult internet issue with my ISP and the Australian NBN (different company that owns the network infrastructure). A while ago I was complaining about my crumby internet service and my ISP managed to force the NBN to do some investigating, they ended up telling me that the signal noise around my place is too high, so they installed an attenuation device on my NBN NTD, naturally it was a bandaid solution and it helped a little bit, but it is still terrible. I'm wondering if I can use wireshark to look for any kind of tell-tale signs of faulty cable infrastructure (signal reflection/ leakage/ impulse noise/ common path distortion etc.) I'm not an expert with wireshark, but I learned how to check my UDP traffic and it looked like huge swaths of packets get lost into the ether.

EDITEDIT:

I'll put up a packet capture if it helps https://gofile.io/?c=Emk4ZF. I got the capture while spamming refresh on a speedtest website, it sometimes lags out on the first try, other times I need to refresh a few times. I get the error "A socket error occurred during the download test. Please try again later.".
