Speed drop issue

The Ayatolla

I have a UPC modem with 240mb wifi.

When I connect with a Cat5e cable direct to the UPC modem, I get 240mb with a speed test, no issues.

However, I mostly use my own TP-Link router which is connected to the UPC modem with a 1m Cat5e cable. The UPC modem and my TP-Link (which is about 3-4 years old now) have Gigabit ethernet.

When I ethernet directly into the TP-Link, i only get around 120-130mb in a speed test.

I've tried changing the cable linking the UPC modem to the TP-Link router, but the speed still remains.

What could be wrong here? Time for an upgrade of modem perhaps? :-/ Could be there be a setting somewhere on the TP-Link that's throttling the speed?

Is your TP link connected via its WAN port?

Yep indeed it is

Connect a couple of other devices with Gigabit NICs and check speed on them.

Yep I did that, full 240mb from the UPC router but around half that with the TP-Link (using the same Cat5e cable to test).

Could it be firewall settings on the TP-Link?

Which model TP Link are you using?

Don't do this.

The WAN port is treating traffic as a foreign network and applying routing and firewalling. Thats a lot slower than switching.

Configure a static address, DHCP off on the TP then connect it with a LAN port. You'll get the full whack.

Can you do this with the TC7200 modem supplied by VM?

Of course, its just acting as an access point.

How do i configure the static address on the TP-Link. I have the TL-WR1043ND

My UPC router settings page is 192.168.0.1. I don't think i have to change anything here?

Is it this page on the TP-Link? What should typical settings look like?

Thanks for the reply ED E. Not too technically minded. Is this classed as bridging? Does it lead to an issue of "double-natting"?

To put it in terms I can understand Can I purchase a modem, e.g. archer C2, just plug it into the lan port on the TC7200 and turn off wi-fi on that machine?

Okay I think I'm good now. Using Wifi on the TP-Link and ethernet speeds are a lot higher. Thanks!

Can't access the TP-Link router setup page though, it used to be located at 192.168.1.254 but this seems to have changed now since I switched from the WAN port to an ethernet port?

You should have assigned it a different IP. If your VM Router is on 192.168.1.1 then stick the TP on .1.250 say. Do this by disconnecting the TP first.

Its just acting as an Access point, no NAT, no routing. Many routers even have an "AP Mode" that makes it super user friendly. Basically its saying to the 2nd device "Just do wifi, nothing else".

Just so i don't break anything

1. I've turned off DHCP on the TP-Link.
2. I've connected the UPC modem to a TP-Link's LAN port, not WAN.

Here are my settings. Do these look ok?

ED E

WAN doesnt matter now, the link will be down. You could set it to 0.250 instead of 1.250 on LAN to stay within one subnet but its not a huge deal anyways.

The Ayatolla

All sorted. ED E you are a legend.
