A moderator also told you in another thread - his words sum it up best:
I think this best explains the matter after multiple threads that attempt the same things. Apologies you feel they're all different. Out of the respect of the fact it upset you when I requested a moderator close the thread - perhaps you should have the honor of asking the moderator close your topic here.
Really, we had 37Mbps in 2016
70Mbps from around 2019
now were on 200Mbps fibre
I know why its 16Mbps, there are a lot of rural areas with just ADSL not even FTTC
I have seen 200Mbps with that same adapter on my laptop
Real speed not the link speed
I can get 180Mbps with my laptop connected over ethernet
but on 40Mbps with my iPhone over the USB AP
I already have good placement locations for the RE450 and the plusnet router
both upstairs, one near the back of the house one near the front, full coverage wherever you are on the property
Yeah, Sorry about that
I know the adapter is capable within windows
could it be the fact its right next to the 12 volts power input
or would only mains 240 volts cause issues like that
Laptops (generally) are likely to have more capable WiFi antennas. But the key takeaway from this (and every other thread you've had about this 'issue') is that WiFi is inherently inconsistent. There are a huge number of factors that impact on latency and transmission speeds. Some of these are static, some can vary from second to second.
If you want reliable, consistent speeds use wire. Otherwise learn to live with what you have.
Both devices involved in the transmission need to have antennas...
And yet it is.
We've also been over why you're not going to achieve what you want the same number of times (or at least it feels that way). Not stopped you beating the horse into fine pulp though has it?
Yeah, maybe do that. Please don't run OpenWRT on anything. Let some other forum/support service try to explain the same things you've been told here repeatedly. Who knows, it might finally sink in.
By using different hardware. Which is what you were advised to do months ago. This isn't you proving the world wrong, all you've done is proven that you should've paid better attention to what you were told back then.
And it still hasn't got you to the speed you insisted was the minimum you'd be happy with.
I can probably answer on behalf of everyone here. No-one wants a 'final chance' to give you more advice you will inevitably ignore if it doesn't work out exactly how you imagine it should, or have to try and work out what your posts are actually trying to say.
Please just go and buy the RE450. And if that doesn't work, please don't start yet another thread about it. Just accept WiFi isn't going to get you what you want.
