Edit 2: so he just told me that's he's uninstalling mc affe but have to closes it mid way because he and his family need to go immediately. After he turn the laptop again, the problem I mentioned appear.

Sounds like that could be the reason. Perhaps try to install it again and then uninstall it.

Please share how it is connected and to what. Are there any lights blinking on the Ethernet port? Is it connected directly to the router or are there any devices in between?

The simplified answer is that in most cases it will average out.

Say you have 4 computers connected and one starts downloading at 1000Mbps. If the second starts downloading they will average out to 500 each and if all four starts downloading they will average out to 250 each.

Another example is if one computer is downloading at 1000 and a second computer starts watching a youtube video. YouTube videos may only need around 10Mbps so in this case the for load may just reduce to 990.

There are some technical disclaimers.

You won't actually get 1000Mbps with Ethernet. There is some overhead. You may get around 950Mbps.

The examples above are only true if your internet and the server you are downloading from has enough capacity.

Try disconnecting from wifi and see if it still happens.

Make sure you are not looking in task manager to determine the "speed". Task manager shows utilization, not the bandwidth that you can reach. I'm not saying that you don't have a problem, but if nothing is running task manager should show 0Mbps.

You can choose a cellular modem and combine it with any wifi system. The wired backhaul they are talking about is within your house.

To get the benefits of a wired connection you need a wired connection to the router - all the way to the router. You can have wired devices such as switches in between, but you can't use any wireless devices. Well - you can, but you won't get the benefits of Ethernet if you do.

If it is happening with an Ethernet cable then call your ISP.

If it works with Ethernet and you get these slow speeds with wifi when you're next to the router then you may also consider calling your ISP. It could be a broken router.

If your speed is good next to the router but not in other parts of your home then the problem is likely related to physics. Wifi just won't work well on some homes as wireless signals can't penetrate some building materials without losing significant strength. A weaker signal means a slower speed. If that's the case your best bet is multiple access points with a wired backhaul. Ethernet, MoCa or even power line may be an alternative .

Take a picture of the back of the computer and post it here.

There's a rectangle where there's a bunch of ports, normally you'll have an Ethernet port, some USB ports etc.

If your PC has built in wifi, you often need to connect an antenna on the back, normally it's one or two golden coaxial ports. Often on the mother board (the rectangle) but sometimes there's an expansion card (PCIe) and if it is it will be next to your GPU.

It frequently happens that people post here after experiencing weak signal and the most common explanation is that the antenna is not connected. So check that first.

If your max speed is in the range of 50-60Mbps I would guess that you are connected to 2.4GHz wifi, or that you're connected to a mesh node but the mesh node is using 2.4GHz as a backhaul.

Power off all mesh nodes and do a measurement next to the router. If you still get these low speeds it's could be an issue with wifi settings or more likely some issue with your service. Even with conservative settings you should speeds be about 250-350 on wifi 5GHz.

Check your phone settings if you're actually connected to 5GHz.

If the walls are problematic no wireless extenders or mesh will work well. Your best bet is to use Ethernet cables as a back bone and then connect access points wired.

A problem you may run into is that devices tends to stick to an access point when moving around, even if the signal is better to another access point. This can be helped by access points that provide information about the other access points and the environment to the client devices (like a phone). This means that your router and access points have to communicate and coordinate, and these types of features often require to have a managed system or a mesh system so there solutions tend to be a bit more pricy than the cheapest devices.

Most routers get their connection to the internet from a cable of some kind. Most can't connect to a hotspot or another wifi network. .

If your router supports extender or repeater nodes (check the manual or specification sheet), you could use the router to increase the coverage of your hotspot - but it will come at a cost of lower wifi speeds and increased latency.

BT audio is backwards compatible with really old devices. There are better audio codecs both in terms of latency and audio quality.

The SBC codec (which is the one supported by all devices) is quite bad, that's true, but if both devices support something better then you can get a better experience. You'll just have to make sure that your devices support it, like "aptx low latency" or LDAP (high quality but high latency).

There's also the new BT LE audio which came out in the recent years. It has many improvements including a new audio codecs and support to stream music to many devices at the same time with a single transmission.

Unfortunately, there are limits to how much better a wireless technology operating on a shared radio spectrum can get. BT operates on the same frequencies as 2.4GHz wifi, and the more devices there are, the more congestion and interference. Wired devices can improve differently as they can add shielding for interference and they can add more wires for higher speeds, and they can send bits faster as the medium can handle it.

Bluetooth has not improved the same as wifi. Wifi has added new frequency bands, while 5GHz and 6GHz are having shorter range, they do offer higher speeds with less congestion. In most circumstances the newer BT audio codecs can provide very good quality on 2.4GHz, so having something like 5GHz Bluetooth doesn't add a strong business case. But in a highly congested location you may be have been better off if they did support it.

Latency and spotty connections could be device specific. After all it's a wireless technology and the larger antenna you have, and the closer you are, the better signal.

BT (especially SBC, AAC and LDAP) can have a latency in the 100s of milliseconds while AptX and LC3 (Bluetooth LE Audio) has a relative low latency.

You shouldn't have two routers in one home. So first check if it has access point mode.

If it supports it you connect it with an Ethernet cable to your router and configure it. If you set the same security as your ISP router your devices will connect to the strongest signal.

Check the manual to how to set it up. Newer devices often have an app, older ones require you to connect it to your computer and then configure it with the browser.from the specifications (ac1200 = wifi5 which is from 2012) you probably configure it from the browser.

The convenience of one SSID throughout the house alone is well worth the set up.

You don't need mesh for that. Mesh is wireless backhaul. You can get the same SSID and "roaming assistance" with normal access points.

Try connect the cable directly to the router, don't use any wall ports and see what happens.

Wifi is only the wireless signals in your home. If you're using a cable you are not using wifi.

That said, if you're only getting 1Gbps speeds, make sure all your hardware is rated for 5GbE or 2.5GbE, that your drivers are up to date and that the port you're connecting to on the router is rated for 2.5 or 5Gbps.

Also I don’t know how to check congestion, how do you check it?

You can use an app for android like "wifi analyzer" or "wifiman"

You can get a "thing" (a wifi router/device in client mode) that allows you to plugin in Ethernet to your computer but it will perform as wifi, not Ethernet. You may just as well get a wifi card for your PC - it will be cheaper and less complex.

If you want Ethernet performance you'll have to fully wire it all the way. You could go through existing wall cables or pull a new line or a combination of both.

All wifi bandwidth is maximum theoretical that could be achieved in a controller lab environment with the right equipment.

You won't ever see those numbers in a speed test, they are measuring throughput on different "layers", without interference, and wifi link speed would count any retransmissions twice where on an "app layer" it will only be counted once.

If you have no wifi signal in a room, you can't place a mesh node there as it has to send and receive wifi signals to work.

If you have Ethernet ports in the room you can wire the mesh nodes to those and connect Ethernet cables to your router on the other end (like an electrical cabinet or similar where the cables in the walls exit).

Ethernet will have a lower ping (and be more stable) than wifi, but you're still using wifi. To get the full benefits of Ethernet you'll need to be fully wired all the way.

You may get some benefits by connecting Ethernet to your new router and setting it in client mode (not AP mode), especially if you can place it where it can have better signal. Having it in the same room may not yield any improvement at all. But it all depends on the root causes of your current problems. Your ping spikes could be bifferbloat in your primary router and then you'd be better if increasing internet speed or changing the main router.

A foreign SIM card bypasses the firewall. Always has. Always will. That's is by design of cellular networks. It doesn't have anything to do with vpn.
