I have already upgraded storage to SSD and RAM (now 16 MB). internet speed at home has no problem because I have another laptop.

windows 10 is now in the laptop.

but the speed is still very slow 1.33 mbps download and 0.36 mbps upload.

should I upgrade the network card? which one is better for my laptop?

    The oem Wi-Fi/BT card fitted to your Aspire VN7-793G laptop should be a Qualcomm Atheros Wireless AC Wi-Fi adapter QCNFA344A NFA344A Wi-Fi Dual Band + BT4.1 Bluetooth 4.1 NGFF Card - this card is a 2.4/5G Wi-Fi and 4.1 Bluetooth, which should be 1000 times fatter than the speeds that you are getting from your oem VN7-793G laptop now. also check your modem if that is not faulty as a download speed of 1.33 mbps and a 0.36 mbps upload is slower than a dial up and there must be something wrong with your card or modem. Also connect your laptop with a LAN cable and see if the speeds are faster, as if they are, then the Wi-Fi/BT card is faulty and needs replacing. Good luck

    I have found my network card is Qualcomm Atheros Wireless AC Wi-Fi adapter QCNFA344A.

    when I use a LAN cable very fast.

    what is the reason for slow speed?

  • @Lili2

    Lan cable connection is a direct connection between router and computer. It will always be very faster when compared to wireless speed. Wireless speed will always be very less when compared to the wired speed.

    You can increase the upload and download speed by using lan cable.

    In my house , i use use lan cable for my computer and i work with 400 mbps speed. If i use wireless on my mobile then upload and download speed is very less.

    You can also purchase a external wireless adapter to increase the speed of network. You can also upgrade the router to wifi 6 to increase the network speed.

    You can run the network speed test and check the upload and download speed on lan cable and wireless connection and you will really feel the difference.
