Riddle me this... TPL Deco M5 on FTTP vs VM

Hi all,

This has me perplexed, but it could be as simple as me not understanding how various internet things work...

I've recently changed ISP to Giganet and have their 900/900 service. Everything as of today is working as it should, wired connection to my macbook is 900/900 or thereabouts.

However, when I go to my usual connection setup...

ONT > Ethernet > Deco M5 (main) > Wifi > Deco M5 (secondary upstairs, always gets full speed despite the floor/ceiling) > Ethernet > PC

...it drops to 500/400, 600/400, and variations of that, all roughly adding up to ~900 to 1000mbps.

With Virgin Media, when I had the same set up, it would always hit the amount i've paid for, for 1gb service (nearing that) then max for the 500mb service and max for the 350mb service.

Is there a restriction on the deco ports? Or is there a setting I should change to account for the change from cable to FTTP? or because of the increased upload bandwidth, it now has to balance with the download bandwidth?

Thanks! :)

Looking at the specs it will depend on which wifi channel they are talking to each other over.

AC1300
5 GHz: 867 Mbps (802.11ac)
2.4 GHz: 400 Mbps (802.11n)
 
Sorry, are you saying that your mesh Wi-Fi used to support a 500Mbps Virgin Media connection but now when you do a test on a 900Mbps connection you are getting between 500 and 600Mbps?
 
Oh crap, sorry guys, I missed out that I used to have a 1gb VM connection too, then 500 then 350. That’ll teach me for not reading back over my post properly.

@Glanza I suspect that it probably did max out around the 867mb mark on the 1gb connection. (Not paid for 1gb for over a year so memories hazy)
I’m wondering then why the Giganet one isn’t doing similar?
I assumed gigabit ports did 1gb!

@Caged, Yes, so in light of Glanza’s info, I’m wondering why it’s not going close to the limit of the Deco?
Is it because it only hits that limit if the upload speed is low like a VM connection one? Whereas the Giganet FTTP is 900/900 so it has more of a load from the upload side?

Sorry, if that’s bad logic…

It's not physically possible for a Wi-Fi mesh with a PHY rate of 866Mbps to deliver 1Gbps to you, you were probably seeing dodgy speed test results on VM. Getting between 5-600Mbps on Wi-Fi 5 (802.11ac) is a good result.

No, I get that part now. But how come it’s not meeting the upper limit of that, like I recall the original connection doing?

The only difference is it being cable essentially with a different upload rate. I guess that’s what I’m trying to understand.

Are you sure it met the upper limit? Nothing has changed in your setup at all other than the Internet connection? If you were connected to a mesh node backhauled over 802.11ac and seeing 800Mbps then you probably had the most perfect environment in the world for Wi-Fi performance.
 
Promise, it was genuinely 800+. I need to see if I saved any screenshots anywhere from back then.

And I’ve tried the Eero Wi-Fi with my MacBook, and that gives ~600 too right next to the router. Hence why I was wondering if upload made a difference as that and the different delivery method of DOCSIS vs FTTP was the only thing I could see that was different.
 
At this point I'd suggest to monitor the CPU usage and if you're maxing a core out when transferring data then it's likely the limit, but lol as if you're getting CPU usage out of a TP Link box.

What if you put it into AP-only mode and use the router that Giganet gave you?

Yeah I could give that a pop. It’s not the end of the world as it’s still great speeds while being cheaper than VM. I was just curious more than anything.

Appreciate your input :)
