Introduction
My internet download and upload speeds are advertised at 30mbps down and 5mbps up, however since ~72 hours ago I've been experiencing heavy interference resulting in poor connectivity to the internet.  I've contacted my ISP technical support and running through their troubleshooting methods such as restarting the modem has not helped at all.  They have said that there are no internet outages in my area and my neighbors who are also using Oceanic Cable are not experiencing any problems with their internet access.
 
To summarize my situation, my internet will disconnect on its own on random intervals of a few minutes to a few hours, only staying offline for a few minutes then reconnecting successfully.  While the internet is connected I experience a mixture of stable connection with bursts of really bad ping spikes and slow speeds.  Sometimes my download speed will return to 30mbps for brief periods of time, then will plummet down to 1 mbps or lower.  My upload speed remains consistently below 2 mbps dropping as low as 0.12 mbps.
 
They've scheduled a technician to come in this coming Monday, but I thought I'd post here to see if anyone might be able to help in the meantime.  I'm prepared to run whatever tests necessary so please let me know what I need to do  :)

It looks to me like typical line issue and I suggest you wait until Monday.

You could check couple of things by yourself in a meantime.

 

If router is involved, bypass it and connect straight to the modem.

If you have more than one computer do all of them display same issue?

What happened to me once was a case of bad splitter so if you have any splitter involved (most of us have at least one, splitting the signal to TV/computer) try to replace it.

Thanks for the response :)

Yeah, my television and internet share the same connection so there's one splitter between them and another between the wall as well.  

I'm going to have him test all my coaxial cables, the splitters and the modem.  

Hopefully one of them just needs a replacement.
