r/ethernet

Hi. my superfast broadband was installed and is supplied by Fibrus. I have a Fibrus ONT, connected to a eero router. I have 2 more eero routers. I want to eradicate EMF and wifi entirely and use ethernet cabelling to 4 rooms in my home.

I was told by fibrus today that their service can only be provided by wifi. Has anyone come across this and is this true? Surely they can change the setting at their end to allow me to eradicate all wifi in my home?

I am needing to drop a cable from my router in the living room through the attic to my office. I will need about 100 ft just to be safe. My ISP is supplying 1G but I plan to upgrade to 2.5G when they have it in my area in a few years.

What cable brands on Amazon provide a reliable, safe Cat 6/6a for traversing an attic space that can get well above 130 during the summers? A link with some quick spec breakdowns for a newbie would be very much appreciated. It may run between the studs where my outlet is wired if that matters.

I've seen the prices of plenum and riser cables that I could crimp myself, but I don't need 1000 ft and am trying to buy only what's needed to safely get the job done. A lot of off brand stuff on Amazon sketches me out so if you have success stories with some brands offered on Amazon that can be used in hot attic spaces I'd love to see what's actually good for home use. I see Monoprice popping up on some older posts and am curious if that's still correct to use for my case.

Thanks!

Edit: thank you to the person/bot that took advantage of this being my first post on this account by downvoting it, hope that doesn't impact me getting the solution I need.

Edit 2: I really appreciate everyone helping out! Hopefully I can get my PC to do better than 15 mbps soon!!

So here's the situation because I'm losing my mind over this.

My laptop suddenly started getting extremely low download speeds on my home network only. Upload is mostly normal. Download can go as low as 0.08 Mbps. Websites fail to load, downloads stop midway, and I also get packet loss (2–3%).

Important details:

• This happens on BOTH Ethernet and Wi-Fi
• Other devices on the same network work fine
• My laptop works fine on OTHER networks
• I tested with another Wi-Fi and speeds were normal there
• I reinstalled Windows completely
• Reset network settings
• Reset router to factory settings
• Changed DNS, MTU, MAC address
• Disabled IPv6
• Reinstalled drivers
• Tried direct connection without router
• Speed link shows 1.0 Gbps normally

One weird thing:
ipconfig /all showed a DHCP lease expiration year like 2162 at one point.

Laptop:

• Intel(R) Ethernet Connection (3) I218-LM

At this point it feels like my laptop specifically hates my home network. Has anyone seen something like this before?

I'm out in the field trying to clean up a messy network closet by making custom-length Cat6 cables to replace some 10-foot slack. I've stripped the outer jacket and aligned my wires according to T568B, but now I need to actually secure them into the plastic plug.

so i just read that russia is basically admitting they cant ban vpns and ngl this is wild because they been trying so hard to crack down on everything lately but apparently their own banks and businesses need vpns to function so theyre stuck like imagine being a government that wants total control but you cant actually pull it off because your entire financial system depends on the tech youre trying to ban thats lowkey hilarious and also pretty telling about how important vpns actually are i got family over there and they been using vpns forever to access stuff and i was always worried they might get in trouble but now knowing that even the government admits they cant stop it is actually reassuring af like they basically threw in the towel kanyone else got vpn stories from restrictive countries or am i the only one who finds this stuff interesting

We got the keys to our new built, and I could see 4 cat6 outlets in 4 rooms i.e. 2 bedrooms upstairs, living room and dining downstairs. I see 4 unterminated wires in the utility room which I assume would be the ends to 4 cat6 outlets spread across the house.

However, today when I opened the panel beside the cat6 outlet in the living room, i again saw 4 unterminated wires inside.

This has grandly confused me and I need some help understanding. What I was planning was since the router would be installed in the living room, I would take a port from the router and plug it into the cat6 outlet. Then in utility room, i would take the unterminated end coming from living room, and put that in a switch as input, with 3 outs where i connect them to the 3 remaining unterminated wires in the utility room. Now, the discovery of additional unterminated wires in the living room has thrown me off track.

I'm in a situation where the only way to connect my Switch 2 to the internet at home is to have my PC connect to the wifi and the switch connected to the PC with an ethernet cable. (I can't mess with any of the wifi router settings so just don't bring up the wifi) I've been able to connect my switch to the ethernet befoe and the first time all I had to do was plug it all in and it works. However every few days, the connection breaks for some reason and I have to scour the internet for settings to change. So for I have always been able to fix the issue but today nothing I try works.

Has anyone else had this issue?

Why did it all work so smoothly the first time and then get worse?

Does anyone have any ideas to make the connection work permanently?

Things I've done so far:

1. manually set the IP adress on the switch and my ethernet port.
2. set my network to private.
3. make a .bat file that closes and reopens sharing on the wifi network control to "reset" the connection between my PC and Switch.
4. Manually set the DNS on my switch

Straight to the point is, my ethernet will stop working while doing heavy load like downloading stuff and play games even though doing normal stuff is mostly fine, after i change the Speed & Duplex thing in the ethernet properties to anything but auto negotiation, it work perfectly without any problem, it has been like this for a while now and i cant fix it, dowloading is slow and so is everything, does anyone have an idea how to fix this? Im using windows 11 25H2 26200.8246. Sorry my english is bad

edit: i also have an extend ethernet cable

what i have to do to play normally

1. used an ethernet cable for the first time (cat6)

2. done speed test

3. wow high download speed

4. turns off pc

5. leaves house and comes back later

6. turns on pc

7. downloads game on steam

8. download speed has gone down significantly(60mbps)

9. wtf

10. does speed test

11. download speed has gone from 980 to 68 (both in megabits per sec)

12. why

So my internet stopped working yesterday and i couldn’t figure out a solution all day i thought that maybe the cable was broken because when i troubleshoot it says “ethernet doesn’t have a valid ip configuration” and “ethernet cable is not properly plugged in or might be broken”.

I just bought a new ethernet cable and plugged it in, it still doesn’t work. I connected the new cable to a network extender that uses ethernet to see if the new cable works and it does. The network keeps saying it is identifying network then connected then not connected and keeps switching like it cant stay connected.

Is this an issue with my motherboard? And is there any way to test if it is so i can get it replaced.

After getting a new computer (prebuilt with new specs), my Ethernet barely runs anything. Videos play at the lowest quality and still struggle to play, I can’t play games, etc. Internet speed tests show Ethernet runs at 679.8 Mbps download and 20.2 Mbps upload, while my Internet runs at 227.5 and 13.7 respectively. My Ethernet cable is a Cat6 flat cable and was only bought a few months ago, and ran well on my previous computer, plus it runs through a splitter. If anyone has ideas as to why it runs everything terribly yet displays high speed please let me know, I’m happy to answer questions. Thank you!

Edit: after messing it seems to be more of problem with web browsers and things like discord streams. Only have this problem when on Ethernet, though. Things like YouTube videos CAN run but at a considerably slower level than Internet, as in barely being able to play even while at low graphics, while on Internet videos can run at max quality with no issues. Trying other browsers does not seem to change the issue.

So a few days ago when I logged onto my laptop I had the most strange thing happened. I’m hoping someone will be able to tell me why because everyone I’ve spoken to about if so far is stumped.
When I logged on, it said my laptop was plugged into an ethernet. Issue? I dont have ethernet. No cable, nothing. It was called (MY WIFI NETWORK) 2, and when I pressed on it, it wouldn’t show me the wifi bar, it was just completely gone. Can anyone help me to understand why this happened?
