No 1GBps speed from WAN

Technical Support for Routers
1

Hello,
have a problem which I can not solve.
I have 1Gbps ISP wan connection via PPPoE.

Tested directly on modem and I get speed app 800-900mbps. Used same cable to test speedtest from modem to PC.
2)All lan connections (router-switch-my PC) are 1Gbps. Confirmed on all devices that they connect 1Gbps. Used same cable to test speedtest form modem to PC.
But when I run speedtest on my PC (tried a bunch of them all the same result) I get max 100mbps speed. No SQM enabled. Router is Flint2. Please help!

Hi,

Hmm, is the pc the only device reaching 100mb/s or all?

Also you said that you have checked that all ports are 1gb/s, including the switch, do you mean you also checked on negotiation rate?

A little off topic:

I was thinking lately since i might want to upgrade my equipment in the future, also about how they terminate patch panels especially since newer cables don't like any core exposure, they need keystones now to properly shield because these older patch panel ports may won't negotiate anymore on these newer speeds plus the core exposure on cat6+ is actually not usual.

now comes my realization: besides some households may still have bad cables with bad terminated coring (i don't think this is your issue, maybe on its slights a 100mb cable), but maybe they also have a old 100mb/s backhaul patch panel?

Actually it's something very overlooked, but i have seen a few US videos of homes which had it, which is for me unusual but likely very normal in some places.

Could the patch panel be the issue if any?, because 100mb/s is a very generic value.

3

Just to be clear. Is there a switch between a Flint 2 router and a PC??

Remove the switch out of the equation and connect your PC directly to the Flint 2 router.

negotiation rate on all devices is 1000mbs full duplex

5

Have tried that. Still 100mbs.

6

Are you sure you're not confusing bits and Bytes?

Is the ip in the proper range or has it been assigned some random ip that isn't in the pool?

Does it do the same on dhcp?

7

no all is mbps. DHPC works fine. For mine PC have manual ip.

8

I am assuming your PC is a windows client? Have you check your network adapter on Windows to see what the link rate is reporting there?

You can also try the "ethtool" command. Navigate to Luci and login (same gui username / password) find: Network > interfaces and then look for the interface name in question, for example eth1

Load a terminal Window (Termius app on android is good or Putty for Wiindows) Login to the router and run this command (changing "eth1" to the interface port names you wish to check)

Command:

ethtool eth1

This will then report the stats on the port which might help diagnose a little further.

9

Please run a speedtest on the router itself to see if the router is already part of the problem:

10

I get:
Settings for pppoe-wan:
No data available

11

Strange. Check the correct interface name. I'm sure yours is eth1. Also follow @admon post.

If your capping at 100mbits then it must be something to do with cable or link speed negotiation as it's too coincidental that it's around the same figure / speed as a "fast ethernet" link.

12

do not have eth1 interface. Checked cables. Negotiation shows on all ports/devices 1000mbps full duplex. Like said tried with same cable speedtest from modems which shows 600-800 mbps. Then tried with laptop on router which shows 80-120mbps. Same on my desktop PC. Yes is strange issue.

13

Please check on the router itself as well. Run those commands I linked.

14

ok. Found it. It was Packet Steering option. When I disabled it everything is ok. Thnx for help everyone.

15

When you say you disabled it, what exactly did you do, which settings and where? Reason I ask is that it might be helpful for others if they have the same issue.

16

I just uncheched box in Luci. Network- Global network options

17

Ah ok. Surely this shouldn't be required, maybe it's a bug in the particular firmware you are running...at least you have figured out a fix for now.
