S4 Deco with EE Router

iEddiez — Fri, 29 Nov 2024 11:32:06 GMT

Hi all,

I have an S2 Deco Network setup and working as a router.

My hardline from my office is into the EE Router which is attached to the main Deco via Ethernet.

The EE router is also currently in DHCP server mode as I didn't change that when I setup my mesh the first time.

I have noticed that I drop ~200mbps connected to the S4 Ethernet port as apposed to full line speed connected to the EE router. The fibre line is currently coming into the EE router and then out to the Deco.

I don't want to drop speed but I do want my S4 to handle everything router related.
This is due to a network issue where my PC could not see my Wireless Printer.

Any advice is appreciated on how to get this setup.

@iEddiez Why do you have the EE Router connected?

Glorified switcher tbh.

I have multiple Wired connections and I’m using the Router to achieve that at present.

@iEddiez OK, EE Router is primary, Wan port of that connects to the ONT modem.

Deco S4 Mesh unit Main one connected from one of the Deco Lan ports, to the Lan port of the EE Router.

If you are Lan speed testing, connect PC Lan to EE then test, next connect Lan port of PC to Deco and test. If you have setup Deco in Router mode, you may have a slight drop test wise, but you need to send up Pics, the units are not the same, S4 is older tech than the possibly what the EE may be. Need to say what EE Router you have and what service speed also on the FF package.

Thanks for your reply.
Your assumptions are correct.

I can run some speed tests over the weekend.
For now though;
Package: Essentials: Full Fibre Gigabit w/ Smart Hub Plus
Mesh: https://www.tp-link.com/uk/home-networking/deco/deco-s4/

@iEddiez No assumptions made, been doing this for far too long, look at your Deco S4 documentation to what is the best way for operation of your mesh system, nothing you have done is wrong connection wise, just got to watch out what you have in the printer wise side, have the same issue myself, printer on the EE side, but just drop to whatever needed to print.

Thanks.
I certainly want my Mesh to control the IP. As the Printer connects to Mesh, it's my PC that's the outlier and not on the same range.

@iEddiez And that's the problem with having two router's like you have!

Re: S4 Deco with EE Router

So, I know I'd need to disable the DHCP on my EE router but then my Mesh can't see my router...
Again, I'll run some tests over the weekend.

@iEddiez You need to look at the operation mode of the Deco S4 mesh setup, router operation may not be the correct mode but only you know how you wish your network to operate.

Re: S4 Deco with EE Router

iEddiez — Fri, 29 Nov 2024 13:50:58 GMT

Thanks. The S4 can operate in Access Point mode (only the main works in router mode as I am sure you know, so all Satellite Decos run as Access Points already). So that'd let my Router do the IP assigning, therefore putting all wireless and wired devices in the same range.

Not against that, just cannot test that today!

@iEddiez You may be correct, but you need to look at the S4 Documentation, AP mode may have lots of other restrictions applied to it!

@iEddiez your main problem is the spec of the Deco, it is only WiFi5, so max 450Mbps on WiFi and LAN ports throughput not really upto 1Gbps that the EE router can handle.

Maybe time to upgrade the Deco, ignore the EE router and connect direct to the ONT.

Thanks for your help. I've had it literally a month. I'm not going to upgrade already. Speeds are OK for the house usage. Just don't like the idea of missing some Mbps to my PC.

Re: S4 Deco with EE Router

Mustrum — Fri, 29 Nov 2024 15:27:09 GMT

@iEddiez do you have digital voice?

If not set the Deco up in PPOE mode and connect direct to the ONT.

Re: S4 Deco with EE Router

iEddiez — Fri, 29 Nov 2024 15:29:15 GMT

I don't think I do.

Can you not do PPOE mode without Digital Voice?

Re: S4 Deco with EE Router

Mustrum — Fri, 29 Nov 2024 15:46:21 GMT

@iEddiez yes you can. You need the EE Hub if you have DV, but as you don;t then you should be better off without it, even if the spec if the Deco is lower than the EE Hub. The Mesh and other facilities should be better for you.

Re: S4 Deco with EE Router

iEddiez — Fri, 29 Nov 2024 15:41:36 GMT

Thanks for Your advice

I’ll look into that over the weekend and as I understand it with without digital voice that mode will work on my Deco

@iEddiez The settings are relativley simple, and EE even have a handy Help Page - Full Fibre settings - so just the username to set up, password if the router needs it, no VLAN setting.
