Yeah that makes a lot of sense. I will give it a good blow-out too. Thanks man.

Can a router cause packet loss?

What do you recommend? last night the speed wouldn't even load as well on my side

i would say try and get a technician out to check on metallic noise... do you have other electronic equipment in and around the router? Try and plug your router in a wall outlet, without any other electronic equipment plugged in ie Xbox, Playstation, DVD, etc
sometimes your router can get fried, or there is interference at the power outlet, with different voltages going through it. I also suggest getting a replacement router to test, possibly one that is not old or more than 3 years old.

OK so I ruled out:
- Router
- Dust
- Ethernet cables
- Ethernet port on motherboard
- Using a filter to fix it
Guess I just have to suck it up and wait for Telkom to wake up.
Thanks for the advice guys, really appreciate it.

ADSL line was completely down this morning for about 30 minutes. Had hope that they're repairing it, but now it came back and it's still the same.
African time. Have to wait weeks before they even consider looking at our issues.

Does voice go down as well?

No voice this side.

Not sure what you mean ...
Reason I ask is I've found it best to leave ADSL issues out of the equation in cases like this and rather report "noise on line" or "can't receive/make calls" - Telkom seem more adept at fixing voice faults and ADSL problems have a habit of disappearing when the voice side is "clean".

It means we only use cellphones so I have no idea what happens on the voice line.

Pity, the voice line can be a useful diagnostic tool.

OK so after the tech on Sunday found it's exchange congestion (Philemon didn't notify me at all btw, I had to request feedback manually on Telkom's Facebook page), I asked Charl if he knew what I could do regarding getting it fixed ASAP, as the packet loss renders the service basically useless to me.
Turns out there's no congestion at all, seems the techie was bright enough to suck the standard excuse out of his thumb, but not bright enough to actually investigate it. Apparently the max usage on the exchange has been around 80% of capacity. He also said the exchange is one of their latest units, working on their NGN(Next Gen Networks), so there shouldn't be any congestion.
Ruled out router, anything on the PC, and my cables. Charl changed a few things and it went from 15% to about 8%, but still far from ideal. What baffles us both is that download is operating at 100% speed, but upload is only at around 0.2 - 40% of expected speed. Also, my ping is very low, not abnormal at all in that regard.
So 6 days later and still no idea what the cause is. Great.

same my side, tecchie told me back then its possibly congestion. After i ran it with Charl, he indicated that the exchange was only up to 40%. Its things like that, which can royally piss you off, because then you start to run around like a mad man. Its only after the 100th techie, who did a proper test, that he said there was a fault on my router.

Hahaha. Exactly. It's making me ****ing nuts. Luckily you've found the cause. I've ruled out router, and PC, and they've ruled out exchange. So what now? The only thing I can think of, is the physical line between me and the exchange. But apparently my line stats are perfect. So I dunno any more man. I've tested every scenario I can think of.
2nd time in 4 years (different homes each time, same exchange) that it was diagnosed by Telkom as congestion, and it turns out not to be. First time was actually how I got to know Charl, via Twitter. He was again the one that identified the real problem. That time, however, it looked and smelled even more like congestion, as I had ridiculous ping - yet it wasn't that, and within days of him identifying it, it was fixed.
I wish I can tell Telkom to **** off, but I don't have that luxury. I tried Level 7, but I cannot afford their installation costs. Besides, chances are they're likely running through Telkom anyway.

Another example of how abysmal the fault finding skills have become in the network generally.
It is so easy these days to simply "blame the other guy".
The fall guys mostly being the last mile provider (Telkom), which is no longer Telkom, but OpenServe or a combination of both.
BTW, 80% utilisation is at critical levels, does not matter what part of the network we are talking about.
I do not understand why everyone want a "singing and all dancing" router. The higher the line capacity becomes the more important it becomes to be able to "segment the network" into manageable blocks for maintenance purposes.
So someone needs to explain to me the logic of not having a very simple "Line Terminating Unit" (old language), or ONT ( new language on a fibre system), designed to do nothing else but ensure optimal line performance and compatibility with the distant end equipment. No brains, no complicated software, just what is required to run the access network technology.
THEN you had the fancy stuff.

POTS Filter? Rj45 cable? Have you tried replacing all of those? Im guessing yes, but if not, can you try that?

Well to get back on this topic, I discovered something related and very interesting today.
I've had this Tenda N60 Router sitting in my cupboard for ages and just noted the other day that you can install the Tomato and AdvancedTomato firmware on it.
With great pain and effort I finally got it running AdvancedTomato and have been testing it out as my main router for a few weeks.
So in doing so I moved my OpenWRT (TP-Link something or other) Router to the other side of the house to broaden my wireless coverage.
Then I was messing around with LAN Speed Test Lite today and chucking 20MB, 500MB and 1GB files over the network on both 2.4GHZ and 5GHZ to see what the speed differences were like.
Everything is cool up and until you do the 1GB file and read it back from the server and suddenly it starts dropping packets to 192.168.1.1 (Tenda Main Router) and also 8.8.8.8 -t like crazy with only every 5th response coming through.
Bizarrely writing to the server is 100% with no issues.
Throughout this though the OpenWRT at 192.168.1.2 keeps responding without issue so it's not my laptop or the AP in the middle.
Unfortunately while this happens I lose connection to it and it doesn't offer historical CPU/Memory usage for me to track down what the actual culprit is, but I suspect it's simply being overloaded.
It is a cheap Chinese piece of crap and I guess it could even be a firmware problem but I doubt it.

Is anything constantly uploading on your network?
Continuous uploading will cause packet loss. High router CPU usage also.
Most Telkom techs just look at the download db results. Ask for ATUC SNR. think it is ATUC. I have seen download results being fine but upload being horrible. Check power cables close to the telkom cables. Also ask the telkom tech to cut the cables and repatch cable - rust on copper maybe. Also ask them to do same on exchange side and where it joins on pole outside your house if possible.
