Twitch never streams without buffering for me, never has on any ISP, and I mean heavy buffering. No issues with other streaming on Crystal.

Whenever overseas friends send me Twitch streams I just try it out of politeness, but I know it won't work, and indeed it doesn't.

Busy testing here and http://www.twitch.tv/leveluplive for example is fine. Demands around 600KB/s on high as it spikes on occasion though...

I know that earlier this morning there was an issue in Germany with connectivity which may be impacting services after it peers off in Europe. However we're not seeing anything in particular cause problems.

The easiest thing to check is whether it's all Twitch streams or not. If not, then it's the source or that specific server cluster from Twitch causing issues. If it's all streams then it's your connection, which could be caused by a number of things. Knowing how the network is operating, it's just highly unlikely, unless we have specific network notices out, that it's related to us...

I've had Americans, Greeks, Germans, Brits and people from Turkey send me streams. Never works. Always works for the others in the TS chats. Gave up and decided it's due to the 200ms ping. Could be totally something else but I couldn't care less any more.

Latency certainly has an affect due to operating system receive window buffers. It's possible you may want to search this thread for my post on this and see if your receive window buffer on your machines are set correctly. If not, the OS may be limiting the buffer which results in your machine not being able to scale the TCP window size up sufficiently to process the stream bandwidth required. A few commands in cmd and you can check.

Quite sure the post was here in this thread where I went into some detail on how and why this works...
 
Looks like it may be some weird interaction with twitch. Origin is downloading fullspeed and youtube was fine, and hardly buffered around 720p 60fps. oddshot also seems fine.
 
So if the area shows light purple on the Telkom map for FTTH, can you guys check if it's available or get an estimate on when it might be available?

We can't check when it's going to be available, no. That's not something shared with ISPs. We have the same data Telkom display to end users with respect to their fibre...

Well there is something fishy in the matrix. I woke up at 4am to get ready to go to work. I saw there as no network activity - only 2GB of my 13GB queue downloaded since 12am. There was no internet according to the network indicator in windows, but all the lights on the router was green.

It is frustrating to reboot the router every other day (sometimes two to three times a day) to fix the "No Internet" situation, yet there is no network issues? And support cannot give me a definite answer about it when I contact them.

Couple things:

1) if the router suggests DSL sync has been made and auth is successful the likelihood of it being our doing is slim to none.
2) if your PC is indicating no internet then somewhere between your modem and the rest of the local network something fishy is happening.

Now it comes down to diagnostics by elimination. You have to try another modem-router to see if it's the possible culprit. You need to be sure there is no virus hitting your local network. You need to make sure there's no DDOS attack that causes the router to freeze up.

But this does appear to be a router-related issue. And I suspect the router is freezing. Often this happens when they run out of RAM (remember they have tiny amounts of it, and is partly why we often suggest proper power cycling of the router). Also if the reboot solves it but not rebooting other devices, we can narrow it down to the router being faulty - I can confirm no authentication or throughput or sync issues connecting to our side. Can you login to your router when this happens? Likelihood is not, or it's very slow to do so.

Possible reasons: DDOS - eventually causes the router to freeze up entirely. Faulty chip. Faulty router-board. Faulty chipset. Log file getting far too big (disable logging to test). Faulty firmware.

Almost certain you're going to find the culprit by running through this process of elimination...

Thanks for the info. You are correct about not being able to access the router. Never doubted the network, but like I said, it is frustrating if the modem freeze.

Guess I'll have to plug in the billion modem with the new shiny TP-link 8 port gigabit switch, and take my old D-link 2540U to the shooting range for some target practice.:whistle::D

May just be the log file getting too big, a DDOS, or something a firmware upgrade can solve, without "putting it to pasture"...:D

It is already running the latest firmware. By putting it out of my misery, I will ensure it will never give anybody else any issues, ever again.:whistle:

Can assist with a new router. Will be compatible with new stuff coming next year from us... ;)

How can I flush a log file?

Big logs can often be hard to flush. Try bigger plumbing...:D

Depends on the router. Hence the power cycle recommendation. Often needs to be switched off entirely on some firmwares to prevent problems reoccurring (if a problem exists)...

That is why I want to flush it properly. Better air and data flow after the mod:D
