RJ45 to USBC

[JohnD]

I have RJ45 sockets on my home LAN.

But my laptops and tablets don't. They have USB.

Do I just need a cable, or is there an adaptor box needed to "translate " the signal?

I can't add a comms card like I would on a tower.

They surely support Wi-Fi, don’t they?

You will need an adapter as both use different signal types.

I can't add a comms card like I would on a tower.

Why don’t you connect the devices to Wi-Fi?

And if you do mention that it won’t be fast enough compared to not using WI-FI, what exactly do you need that speed for?

What advantage does running an ethernet connection gives that justifies adding an adapter and cable, instead of using WI-FI, especially for the tablet?

You can buy adaptors

or the USB-C version https://www.amazon.co.uk/dp/B0DLPK3388

Now relegated to fringe and seldom required niche items, as the vast majority of motherboards have ethernet built in.

...but not my laptop.

Speed.

Thanks.

Speed.

Unless you’re far from the router/modem, do you really think you’ll benefit from speed?

And if you are I’m sure that can easily be circumvented by switching from 5ghz to 2.4ghz.

For many average users, probably like you too, sincere apologies if my guess is wrong, but modern 5 GHz (or 2.4ghz?) or Wi-Fi 6 connections already achieve hundreds of mbps, sufficient for streaming 4K video, online gaming, browsing social media, texting and video calling, browsing the internet or large file downloads.

So which is it from there that you think Wi-Fi won’t be sufficient for delivering speeds noticeably different compared to Ethernet?

If it was a desktop PC, I wouldn’t have said the same.

Yes.

I think it's supposed to switch itself automatically for best performance. I don't know how to do it myself.

 

[Jurassicspark]

Yes.

Would/have you notice(d), if it was switched to 2.4ghz, the difference? Was it actually checked, and how?

I think it's supposed to switch itself automatically for best performance. I don't know how to do it myself.

Either from the device settings or from the router settings.

I’m sure older devices with outdated Wi-Fi cards are limited to 2.4Ghz.

5Ghz will perform ineffably slow if the device you’re using is a long way from the router.

The question is though, how far away are you from the router?

I tried at 5 metres, and again at 1 metre.

Usually my WiFi is about 125 Mbps, depending on device

The laptop is less than a year old

But I had a large download of new version satnav for the car

And it was only running at about 25

Today it is 35 at 5 metres

Are these devices running on 5ghz?

Checking internet speed while downloading programs isn’t a good idea. It’s best to pause the downloads then check.

Today it is 35 at 5 metres

Which isn’t bad, is it?

AFAIK - I was getting around 40 last time I checked, and it works perfectly fine, well at least to me.

Don't know. Can't see it on Device Care or Connections

The package took more than an hour to download. It was a zip file. I don't gave the size to hand. It took so long that the laptop timed out and I had to change all the sleep and power off settings.
