Hello all,

First of all, I recently got an upgrade from a 400mbps to a 500mbps line, but nobody here knew until I checked prices for a friend lol.
Why is there no info when this happens ESPECIALLY when they increase prices along with their mandatory upgrades? (This happened when we were on 200mbps and got upgraded to a 400mbps, but it came with a jump in price too).

The second part is a question which might sound stupid.
I now have a 500mbps line, it works great, performance across the board is flawless, HOWEVER I do still get buffer bloat when other clients download at full speed. I know I can limit downloads slightly to avoid this, but my question is more so is this still normal for fibre connections at this speed or even fibre connections at all? And is there possibly a way I can mitigate buffer bloat without reducing speed to everyone else?

I am certainly not complaining here, just looking for information on these topics for knowledge purposes.

Hi, all package changes are emailed to all of our customers about the changes.

If you havent received the comms then check your email address on your profile or a spam folder or the likes.

Can you let me know what you mean by bufferbloat when other clients download?

Do you mean your line saturates and you get loss on other connections that are simultaneously running?
 
No you might sigh when I say this, I'd get 50ms latency while somebody else downloads, not much get affected other than this. I was purely wondering if this is still normal for fibre, especially at 500mbps. I'd ideally want no effect on latency when someone caps out the download, and I'm just wondering if there are methods other than simply decreasing speeds. QoS also has it's limits.

Again, purely information based, I have no issue.
 
In fact, since the upgrade and your amazing help last time fixing the long-standing ping issue I had, the line has been better than ever, super happy with the performance. I noticed a couple weeks ago that the net was dropping quite a bit off-peak hour, but I can only assume now that it was line upgrades. Performance other than download speeds have been improved since, even lower latency and faster web loads.

Its not a typical issue, the increased latency is the line saturating. It isnt really bufferbloat per say.

Glad to hear things are good otherwise.

@CoolEscalator will have a look at your profile, which router are you using?

If you know exactly what services are hammering the line when downloading, create specific policies to limit bandwidth for just those services, or even just the entire client device if it's not critical that device has full speed.

There may be a general QoS rule that can just give everything equal available bandwidth. You would have to specify the total capacity typically.
 
Hardware acceleration is on, smart queue's have been turned off
 
Try it with smart queues as that mitigates the buffer bloat. Set them to just below your max line throughput and see if it helps
 
Ah well apparently I'm back to 400mbps, that was a nice 2 days of upgrade :D

Turns out a QoS policy is setting back my downloads to 400mbps, without it I hit 500mbps again? Whaaaat???
