Windows 10: Should I replace my wifi card or the problem is only driver?

I have a brand new laptop and its wifi card is Intel AX200 wifi 6 when I speed test near the wifi which is on the secondfloor of our house it reaches 70mbps then after a few seconds it drops to 50-55 mbps which is fine because our wifi plan is really 50mbps only but when Im at the ground floor of our house its only 1-10mbps when my phone and other devices still reaches 40-50mbps. I tried to change the wifi driver but when I try the other versions even when im at the second floor it only reaches 1-5mbps and when I use a usb wifi dongle at the ground floor it reaches 25-40mbps. What do you think

Laptop WiFi card replacement

Where I stand now:

• I have ordered an exact replacement WiFi card (new, $5 with shipping!) and it is due in next week.
• The laptop owner has to go back home today, so this experiment will be on hold for a bit. I will revive the thread when I get some results.
• Please keep the thoughts and info coming though!
• If this were my laptop I would be doing all kinds of Frankenstein experiments, but alas.....
• If the replacement card does not work I am going to push her towards the dongle solution.
• If I get test antennae, and they correct the problem, I may still push the dongle. Finding new OEM replacement antennae has been difficult so far. I've only found used ones on EBay. Not going that route.

 

Wifi and browser problems with windows 10


I'll tell you how I fixed an identical problem on a ASUS laptop that had run perfectly on Windows 7 and ran well on W10 from January until the Anniversary update in early August. I tried everything I found on this forum and two others. Nothing worked. The last thing someone suggested was disabling the adapter and using a WiFi dongle. Problem continued. Nobody suggested changing the wireless network adapter. I bought and installed an Intel 7260 WiFi card and just used the driver which was downloaded on the reboot after the install. All problems solved!!

I must have wasted two months reading and trying everything. Even the manufacturer support inferred I needed a new machine though they sent me a Windows 8.1 driver to try, with the same result.

I'd suggest contacting the manufacturer to determine if they white list any cards and see if they have suggestions for a compatible card. They may want you to buy another laptop but if the cards aren't white listed, a simple card swap to one compatible with Windows 10 seems to be the answer.

 

Laptop WiFi card replacement

Hi , sorry if i am late on this one , but here are few facts to answer all your questions through out the thread :

- The range of Toshiba Satellite C55 all ships "Whitelisted" a term used on the internet to describe laptops that wouldn't accept a different model to replace wifi card inside .

- There are underground sites specialized in removing white lists from laptop's bioses but they failed with this model (usually they are successful with those not heavily touched phoenix bios laptops but Toshiba heavily modify their's)

- While the majority of Whitelisted laptops won't allow you to even boot a laptop when the card model / brand switch , Toshiba's Whitelisting manages to boot windows but make the card unrecognizable . they do so so you can use the port as an extra M.2 slot to install a small S.S.D drive but not to replace the Wifi card by another .

- When you search for a replacement all you need is to search the model number on merchants website which is : bcm943142y and make sure it shows in listed name .

- There is one of those sold on amazon for 6$ (+shipping)

- The slot on the laptop is M.2 (accepts ssds) and also NGFF (accept small form factor wifi cards) , the card however is economical NGFF so its cut is even smaller than NGFF but still is NGFF standard .

- The only mean to test if the problem is with antenna is to get replacement external antennas (comes in packages of two separate antennas each with a dangling wire to attach to card) which sell for similar price as the card , those antennas however are meant for test purposes only and are not made as a long term solution .

- Debugging logic instructs you try first testing with antennas as when it turns out the problem is laptop's internal antennas then buying an external card/dongle becomes inevitable so you save on card's price and yet have antennas for upcoming debug challenges than rather 2 working obsolete cards .

I hope that answers all your questions .

Cheers
