Question

Internet speed varying from device to device

my dell laptop operates with good internet connectivity even though distance from router is around 1 floor but my new msi laptop operates lower than 200 kbps , why this is so? and how can i fix it? I tried updating driver, cutting of background process running, set some DNS server borrowing from my other laptop.

Answer
Actually pretty normal.

As the devices are not identical the results are not identical. This means to get to the same speed the machines would have to changed to be identical. This bothers many users as they notice speed changes from device to device.

You may find drivers and changing WiFi channels can change the results but you rarely see 2 machines test at the same speed.

Which means that if you are getting over say 50 megabits then it's fine. We only need 25 megabits for UHD 4K video streaming.

can you solve the problem

my dell laptop is much inferior to my msi gaming laptop, but the internet it fetches is around 30 times better than msi, i am not unable to fix this problem , the difference should be atleast in the same numbers not 200kbps to 20 mbps

No.

Since you are asking for machines to be the same in WiFi performance then no one can solve without change to the machines. And I mean real change such as the entire machine to possible WiFI card or router changes. This is unacceptable to most.

The problem is in how WiFi works and implemented. You can not assure anyone that they will get the same performance from device to device.

And the problem got worse as we moved from 2.4 to 5 GHZ. Before you would get variance from 20 to 60 megabits but now you get results from 20 to over 1,000 megabits. That only made the complaint worse.

I can't tell in your post what speeds you are getting as well as how you update drivers.

1. If you tell Windows to update drivers, that's broken and can make matters worse. Some complain this should work but it does not. I am not Microsoft so I can't fix it.

2. There's also the issue that some routers work better with some laptops than others. This is why when a client has this issue the tech goes out with another router to see if that's it. Again I can't fix it because I'm not making a visit with the spare router to see if that's it.

If you feel the laptop is defective, NOW IS THE TIME to talk to it's maker or seller. If they can't solve it, get your refund. WHY MUST YOU FIX THIS?

Answer
For clarity. And if we change the complaint...

The complaint is "Internet speed varying from device to device" which is normal.

If your laptop issue was just WiFi is slow, then I could comment just on that but your top line complaint is not one anyone I know would fix.

NOW LET'S CHANGE THE COMPLAINT TO: "My new laptop's WiFi can only reach 200 Kpbs."

That is something I have solve many times. But you have to do the work. I'm not there to fix it. Here's some common fixes unless it's hardware so let's test if it's hardware FIRST.

FIRST!!! Take the laptop to another WiFi hotspot and test the speed there.

If the speed is still low you take this back to the maker or seller to resolve.

IF the speed was OK at the other hotspot we check WiFi channels. I have found 2.4GHz routers set to channel 14 and the speeds vary like you noted since not all PCs may be set to allow that channel. Fix? Change the WiFi router to choose channels 1 to 11.

DRIVERS: DO NOT UPDATE! USE DRIVERS FROM THE LAPTOP MAKER.

Yes

Yes, as you mentioned my speed around the router is absolutely fine but as long as i go to my room which is in 1st floor it gradually lags , but my other laptop works very fine. that's my issue

Which is expected

In the channel 14 2.4GHz scenario.

And it may confuse those new to this as this issue can affect one device but not the next.

YOU must check the channel to see if this is it. Also, you must know if the 5GHz is in use since that also can drop quickly over distance and floors but I am encountering folk that want a fix but the fix is not always the same which has led to some complaining that no one knows the fix. There's more than one cause of low speed so there are many many fixes. Sometimes you have to change out the router which upsets the owner that has one thing working but not the next.

Test It Like the Man Said

Seriously, R. Proffitt is right. Take the new laptop to a different location, maybe a friend's house. Check the reception (speedtest.net, maybe) near a router then further away.
As previously mentioned, most new laptops have dual-band wi-fi. This means they include standard 2.4GHz band as well as 5.0GHz band. Your laptop may be connecting to the router on one band but not the other. Usually, 5.0GHz provides significantly faster speed if reception is strong. 2.4GHz usually maintains reasonable reception at greater distances or through walls and floors.
Click on Start and type Control Panel. A window opens.
Click on Network and Sharing Center.
Look in the upper area of the window. It should tell you which network you're connected to as well as which wi-fi band (2.4 or 5.0).
You can try changing to the other wi-fi band, or try the troubleshooting option.
By the way, just had an unlikely thought. When you go to your room are you maybe getting interference/conflict from a next door neighbor's wi-fi which is on the same channel? This would be where you change the channel on your router to a different number to avoid the interference.
Finally, failing all this, it's possible that your new laptop has a defective wi-fi chip, in which case you should return it or have it repaired under warranty.
Anecdote: We have a Lenovo gaming laptop which is equipped with two discrete graphics cards. They're housed in slim cartridges that slide in, one on each side of the laptop. Inside the laptop is an antenna wire connected to an Intel 2.4GHz wi-fi chip. Guess what? The graphics card cartridges tend to block some of the wi-fi reception, so it's OK when near the router but really poor reception when moved just one room away. Solution: we added a dual-band wi-fi adapter that plugs into a USB port on the laptop, and it provides excellent reception on both bands. Of course, it sticks out from the side of the laptop a couple of inches but, hey, it works!

Answer
WiFi Frequency Band?

Are you sure both laptops are connected to the same WiFi frequency band? If not, any comparison is invalid. Since your Dell is older (you don't say how old) it may only have a 2.4 GHz NIC inside, while your MSI, being new, will almost certainly have a dual frequency NIC (2.4 and 5 GHz). Because 5 GHz is nominally faster, the usual temptation is to connect to that if available. This is fine, EXCEPT when there is some impediment between the router and the NIC.

Specifically, the 2.4 GHz band is relatively unaffected by walls and such like and is dependent only on distance, while the 5 GHz band is seriously affected by brick walls and concrete.

You don't say how your house is constructed (mine is wood framed with Giprock walls, so doesn't affect my 5 GHz band but it is affected if I go outside, where the brick veneer seriously impacts it.

You said in a later post that performance was fine near the router, presumably with only air between them. Are there any brick or concrete walls or floors or steel frames between the room where the router is and your room on the floor above?

Try switching the MSI machine to the 2.4 GHz band and retest. I have a friend with exactly this problem and his solution is to use the 2.4 GHz band between floors and the 5 GHz band in the room with the router.

Answer
Different Computers Have Different NICs

There are different Network Interface Cards (for wired networks) in different computers, with differing capabilities. Some older ones are slower.

More importantly, there are different WiFi cards for wireless connectivity, with some at 802.11b, 802.11c, 802.11g, 802.11n, 802.11ac, and now 802.11ax. Each successive one is much faster than its predecessor.

But you say that your new computer is slower than your old one. First question is: Have you tried them at the same location? The speed you describe for your MSI is something one would expect from the older 802.11n standard. If the WiFi receiver in the laptop is 802.11n, that's the best you're going to get without buying an 802.11ac USB dongle for it.
