Asus Prime Z370-A Motherboard slow LAN speeds

Asus Prime Z370-A Motherboard slow LAN speeds
Uses Intel I219-V Ethernet Connection Adaptor
Updated from Intel site latest driver ver 12.17.10.7 dated 5/2/2018 and Intel PROset ver 23.2.0.1006

Problem:
Recently went to cox gigablast service. Cox tech confirmed getting 960Mbps Download from the modem. However, the motherboard/network adaptor is only pulling out (as the cox guy put it) in the 300 Mbps range as shown by man speedtest.net tests. The upload is proper about 38Mbps which is normal for a DOCSIS 3.1 over coax.

In the device driver properties, the latest driver now adds a "link speed" tab. Set on auto detection is showing 1.00Gbps Full Duplex and all the Diagnostics show pass. I also tried it to force the 1bps which has a setting. All settings very get it to pull move then 350Mbps.

I get the same speeds if PC is direct to modem or using Ethernet from router to PC. So the router isn't an issue only the MB or the LAN port. Cox guy seemed very sharp and checked many things are all are normal at the modem - except getting to the PC.

Since gigablast is relatively new in most cities wonder if anyone else has had this issue or any brainstorms

Previously was using cox 150/10 on DOCSIS 3.0 and getting about 170/10 - a bit above specs as usual with 3.0.

Upgraded to a Netgear CM1000 modem - which others report works great with gigablast.

have you changed your network cable to eliminate it being the possible issue?

One of the apps on the ASUS CD is called ASUS Turbo LAN Utility.

The initial display shows connection and bandwidth usage and status. Lots of other switches.

Perhaps a slider is out of place.

I have tried modem to PC with 3 different cables think one is cat6 and another cat5e - no difference.

Installed Turbo LAN - is shaping for bandwidth etc.
The cFos Speed test is a bit confusing. Have run 4 times and consistently gets RX speed 2469.69 Kbits/s, TX speed 3207.87 Kbits/s with response time 167.64 ms

Now using speedtest.net getting 6ms pings and DL 287Mbps and UP 37.1. In theory DL should be about 960 and UP is about right since Gigablast is 1000/40 or 35

The setting black window in Turbo LAN is impossible to read so small printing and can't make full screen. Seems designed for very low resolution vs my 2560x1440 and not sure if I change resolution am going to find anything to help the low speed. Have never used a game, am not overclocking and no heavy loading just Internet browsing basically.

You have taken all reasonable steps that I can think of to fix the problem. I've been downloading since rover was a pup and never had a speed problem that was not network related. The ISP tech here can test my line and the area lines for outages, I've had modems replaced and signal strength problems solved.I have joined the local ISP forum for inside information, code updates, etc, ( I can barely resist saying I've seen it all ).

What I have done when this thing happens, and as the ISP fixes it, is to ask for a monthly/daily refund/ discount when the service consistently fails to meet the speeds set out in the contract.

I take the kind of steps you have to ensure the problem is not caused by this computer and after that I do not for a second assume the issue lies within.

 

[davephx]

I am kind of convinced it's not the ISP cox since the tech showed me the meter with 960 coming out of the modem. I really don't need more than 300 for what I do but would be nice to get the full tier speeds. My last gasp will be to try and talk to tech support for Asus since the LAN is on their MB (Prime Z370-A) and tech's explanation that it has to be on the PC side not pulling more than 300 seems to make sense.

My final test - I also have a laptop with a gig LAN but hooked up to lots of stuff including two external monitors, drives etc. When I get time will drag it to the office and hook it up to the modem and see if getting better speeds or not.

ok, let us know

We use the Hitron CODA 4582 Modem in this area.

Here is a recent rescue from a deadbeat connection--caused by the user's router configuration.

" I was getting extremely slow speeds. I have determined the reason: bridge mode. With bridge mode enabled my speeds were brutal. I did not have these problems on previous firmware versions. I have a high end router with a good CPU. Anyhow, once I disabled bridge mode, I got the full gigabit speed again right away. Here are the steps for those of you that want to do this:



- log into your CODA modem and enable the residential gateway

- log into your router and disable DHCP

- set your router's IP address to xxxxxxxxxx

- hit "apply" for both (I did the CODA modem first; I used two tabs to apply them in quick secession)

- while the units are rebooting themselves, connect an ethernet cable from one of the CODA modem's ethernet ports to one of your router's ethernet ports (do not use the WAN port on your router; just a regular port) "

A Hail Mary for sure.

Not using as a bridge. Might try using direct IP but something else is strange!

I checked my cell phone using Wi-fi and it is getting about 800Mb down near the router and about 600Mb about 30 feet and a wall away using speedtest.net. So, the router is putting out at near 1000 specs which is also what the Cox tech said when here.

Going to my laptop I am only getting about 150Mb with build in gig wireless adapter. However, if I go to the properties of the adapter shows about 600-750 Mb and keeps changing. I have tried both using 2.4 and 5ghz bands and speeds about the same just slightly better on 5g.

Back at my PC looking at properties of the LAN it's showing steady 1Gb/s. Not sure if this is just the speed of the LAN itself or actually what it is pulling - yet speedtests only about 300Mb. And I keep confirming it is 300Mb not mb - get confused between bits and bytes 🙁

I have also tried different server options on Speedtest and while they vary greatly it's never more than about 320Mb down.

After lots of research on Amazon, I ordered a Netgear Nighthawk AC1900 USB adapter for $62.11 which they will deliver tomorrow (free shipping). I will try that on both the PC and Laptop and see if that pulls better speeds on actual network connections measured by speedtest.net!
