New system help
Just purchased ax72 router and added an re705x. The extender is getting good speeds on mesh system. I connected an ethernet cable to the port due to an older (not wifi 6) devive. The speed is poor on this device (56) same with wifi to it. But overall speeds are over 350.

Hello @Jasond75
You're correct, this is almost certainly a limitation of your TV's Ethernet port, not your network setup. Here's why:
TV Ethernet Port Limitation:
Most TVs, especially older models or those without WiFi 6, come equipped with a Fast Ethernet (100 Mbps) port rather than a Gigabit (1000 Mbps) port. In real-world conditions, a 100 Mbps port typically delivers 60-80 Mbps actual throughput, which matches exactly what you're experiencing. Since you confirmed that:
• The router's Ethernet port delivers 500+ Mbps
• The same cable to the TV only gets 70 Mbps
• The extender's WiFi achieves 300-400 Mbps
This clearly indicates the bottleneck is the TV's hardware, not your extender or cables.
For streaming purposes, this is still more than sufficient for 4K content (which typically requires 25-50 Mbps).

Hello @Jasond75 ,
Welcome to our community.
What is the model of this specific device?
May I know if your network topology diagram is as follows:
AX72—RE705X—wired device
(Note: — stands for wired connection,)))((( stands for wireless connection )
If you have a different cable, please try it.
Please connect it to the router directly for a comparison test.

@Joseph-TP i purchased an ax72. Have 500mbs unlimited internet. Have three floors. Have it mounted on a wall high up on middle floor. On that floor and above i get decent wifi coverage. Bottom floor seems quite poor wifi. Added the extender and get speeds on 5ghz band wifi of around 3-400 which is good. I have an tv thats not wifi 6. So i use the extender via mesh to the router and then connected the tv via the extenders ethernet link. The speed is still poor around 60. While the extender is still running on wifi at around 3-400. Similar in other parts downstairs the wifi seems poor. Sorry new to this

@Joseph-TP quick update. Tried changing the cable to cat 6 and similar result when connect the extender to tv via cable but leave it on wireless. When i check the ethernet port on router i get correct speed of over 500mbs. When i connect same cable to the tv i only get 70 max. Therefore is it the tv wifi/ethernet capabilities?.
