Ethernet speed capped at 100.

[tipsy]

Link speed (Receive/Transmit):    100/100 (Mbps)  
Link-local IPv6 address:  
IPv4 address:    
IPv4 DNS servers:    
Primary DNS suffix:    bbrouter
Manufacturer:    Intel
Description:    Intel(R) Ethernet Controller (3) I225-V
Driver version:    1.1.4.43
Physical address (MAC):    

 

 

So, I upgraded my internet speed from 100Mbps to 200Mbps, but on PC, the speed is stuck below 100Mbps. On mobile, speed is fine. I talked to the ISP, he said the problem is at my end. I need to update drivers. I tried a few steps here and there, but I couldn't get the problem fixed. 

 

1) Tried updating the driver via the device manager (I'm not sure they got updated or any other way  to update them) 

 

2) via device manager, updated setting for "speed and duplex" to "auto-negotiation" (which was "1gbps full duplex" previously).

What cat cable do you use?

MOVED what I first wrote here to the bottom of the post! 😄 

 

My ethernet cable from my gateway to computer is a CAT-5e.  AH, it looks like CAT-5 is limited to 100mb! 

 

@Leatherface May be onto something! 😄 My speed is 640mb up and 39.6 down.  I will have to check my provider now to see if that is what I should be getting.

Here's a breakdown of some common Ethernet cable categories:

Cat-5:
.
Supports 10/100 Mbps speeds at up to 100 MHz bandwidth, suitable for basic home and small office networks. 
Cat-5e:
.
An enhanced version of Cat-5, supporting 1 Gbps speeds at 100 MHz bandwidth, suitable for home and small office networks.

You could try turning your modem/router/gateway off and on to make sure it "understands" the upgrade you paid for. 

You could also run the "network troubleshooter" by right-clicking on the taskbar icon (on my system, far right). 
From that icon you can 'trouble shoot problems' and 'open network and internet settings" (if you have Windows 10, like I do).

ALL CREDIT to @Leatherface !!!

 

What cable type did you change it to, or was the cable just broken?

The current cat cable was old, and there was no print on it mentioning what type it was. So I found a new spare cat5, got it replaced, and boom.

Sorry for the late response on this topic, but to get over 100Mbps, you need a cable above Cat5, at least Cat5e.

@tipsy --> So, if you ever upgrade for 1Gbps, make sure your total BW doesn't cap 100, otherwise you should change your current Cat5e to CAT6.
