Realtek PCIe GBE Family Controller stuck at 100.0 Mbps

[kris_20]

I just got fibreOP installed in our house, and to my surprise cannot breach 100Mbps on my wired connection. I've been Googling, trying to figure this out, but nothing is working.

I've confirmed my ethernet cable(s) are CAT5E. I've set "Speed & Duplex" to "1.0 Gbps Full Duplex", and installed the driver listed here: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&DownTypeID=3&GetDown=false (Selected the windows 7 one because I'm running windows 7)

Can anyone suggest anything else? I'm so confused. Shouldn't this be working??

EDIT: I just tried going through a router and the "Speed" value on "Local Area Connection Status" changed from 100 Mbps to 1GB, but when I did a speed test it was still coming up less than 100Mbps.

Are you sure the ISP did not mess up and provision the connection improperly. I normally ask them to run speedtest on their equipment while I stand there.

Pretty much you want to leave all the setting set to auto it works better. I forget if windows 7 shows the negotiated speed on the nic information but it should.

Pretty much the only thing that can cause this are bad ports in your equipment....extremely rare. or some problem with your cables. It generally is not a driver because the negotiation is done at a very low level in the hardware.

Used to be you could just read the side of the cables and look for eia/tia but there is a lot of fake cable that is made from CCA (copper clad aluminum) or uses wire that is too thin. You want cat5e or better certified cables. I would try a different cable. Maybe borrow one you know has worked at 1g.

Like I said all the cables have CAT5E on them...

I tested the speed on a WiFi connection on my laptop and am getting full speed there. It's just this wired connection that's a problem.

If I were to buy a WiFi adapter with a high enough speed, could I plug that into my PC or would that be restrained by the Realtek hardware being stuck at 100Mbps?

Also wonder if I should try upgrading to Windows 10...

If there is something wrong with the realtek hardware it will have issues no matter what you plug this into.

You need to find another piece of equipment that you can use that you know works properly at 1g to test stuff. There are only 3 things it can be. The port on the router, the port on the pc, the ethernet cable.

Thanks. Basically I am using a wired connection from an ethernet port running from the modem to a port in the wall in my office. I unplugged my entire PC and brought it downstairs to the modem and plugged it in directly, bypassing the port in the wall. Suddenly I had 300Mbps.

So, I guess the problem is the port in the wall. BUT - the mystery is not solved. Realising I could not use the port in the wall anymore, I went out and bought this: http://www.bestbuy.ca/en-ca/product/linksys-linksys-wireless-ac-usb-adapter-wusb6300-ca-wusb6300-ca/10278024.aspx?path=94ecbccbd4f1e295842187b901aa9570en02

In the "Wireless Network Connection Status" window, a speed of 650Mbps is being reported. However, when I do a speed test with my ISP, I am getting only 135Mpbs over wifi with my new adapter... With my Macbook, also on Wifi, I am getting 300Mbps+...

Any more ideas on what I should do next?

Thanks again for taking the time.

Wifi number are marketing lies. They do crap like add the 2.4g and 5g speeds together, except you can't use both at the same time on a end device. The rates they state have transmit and receive added together. This would be like calling a 1g ethernet cable 2g...even though ethernet can actually run that fast.

It really depends what wireless card you have in your macbook but the numbers you are getting is much higher than average. The device you bought for your pc is using a 2x2 mimo 802.11ac feed at best. The 135 is more or less what is to be expected.

I would spend your time trying to fix the wall jacks. Make sure all 8 wires are in the correct order and appear to be connected solidly on both ends. If that looks pull the wire lose and cut about 1 inch off and repunch the wires down. You can get a cheap plastic punch down tool at any hardware store.

Wow, who knew switching to FibreOp would be so complicated : )

Thank you very much for the info.

I agree the wall port needs to be fixed but I don't know if it's inside the scope of my ambition/know-how. I suppose I can take the plate off the wall and have a look.

Final question: Are there any USB wifi adapters that are going to let me use the 300Mbps download speed in the meantime? https://www.amazon.ca/s/ref=nb_sb_noss_1?url=search-alias%3Daps&field-keywords=wifi+usb+adapter&rh=i%3Aaps%2Ck%3Awifi+usb+adapter

I also have been quoted a price by my PC's builder for an internal WiFi card: TP-LINK TL-WDN4800 Dual Band PCI-E IEEE 802.11n - Wi-Fi Adapter - http://www.tp-link.com/us/products/details/cat-5519_TL-WDN4800.html

Would that be fast enough or is that a marketing lie?

Thanks Bill.

Many keystone jacks (that is what the wall port is called) include a plastic punchdown tool. Replacing the two wall plugs may be the simplest thing. IF you have 6inches to a foot of slack at the ends, I might just get new cat5e or cat6 wall plugs and replace both ends. There will be color code markings where the wires connect. Follow the 568B color coding on BOTH ends.
