    Did you remove both antenna coax cables before you pulled the card out?

    Open Device Manager. Click 'network adapters' folder. Right click properties wifi card. Click advanced tab. Click preferred band. Try 2.4GHz band first. Check speed test . If still the same, Try 5GHz band. Check speed test again. Report back with results.

    Gently pull the two coax cables off the card's coax pins. Then re-seat the card a few times in its mainboard socket to help clean its gold colored contacts. Replace the coax cables, Make sure the white and black connectors go to the same pins. Test again.

    If still no improvement, did you actually add the SSD or anything else new yet? If yes and if it was an m.2 SSD card, please remove the m.2 SSD card and test the wifi card again.

    Ping is an upload to server & download to laptop response time. Same 11 msecs.

    Go to the command prompt. Then enter 'ping (your server's ip address)' to if it is the same upload-download time. If it is the same 11 msecs, then open Device Manager again. Right click and uninstall the wifi adapter driver.  Then exit Device Manager without reinstalling anything. Shut down Windows normally. Turn the machine back on and let Windows automatically re-detect the wifi card and automatically re-install a fresh copy of its driver.

    3 ms ping is more in line with what I'd expect. 11 ms seems too long for both the TPLink & laptop adapters. Did you have to install any software in order to accomodate the m.2 SSD installation?

    No the m.2 didn’t work either so I removed it and no software for it

    (1) Was this perhaps an m.2 nvme?

    (2) What is your full A5 model number? For exampe, A515-54G?

    Was the SSD an m.2 nvme card or an m.2 SATA card? What is the SSD brand and model number?

    No sorry. That model is an m.2 SATA card if it appears like the one below with the two slots, not nvme card. It should have installed with no issues unless something is wrong with the card or the mainboard's PCIe bus to which the wifi card is also attached. When you installed the SSD card and removed the wifi module, was the battery disconnected?

    I installed this into a separate slot near battery, I didn’t bother with the network slot, and I didn’t remove the battery i just shut down the lap

    >>> I didn’t remove the battery>>>

    Did you at least disconnect the battery connector from the mainboard?

    No, I thought that the battery is pre installed, so didn’t remove that

    OK. Go to https://www.slt.lk/en/contact-us/general-feed-back   Fill out their form and ask if they have their own speed test to help troubleshoot your wifi card since it suddenly seems to have experienced a download bottleneck. Nothing more needs to be said. You may also get a chatline popup that you can ask the same questions.

    If SLTMobitel can't help and their speed test yields the same result, this machine should still be under warranty. I then suggest that you click this link. Click your country. Click the support link that appears near the top of your country's ACER webpage. Enter your machine's serial number id (SNID) and arrange for warranty repair service for an apparently defective wifi module.

    The warranty sticker above the screw is removed, will the warrant valid after that?
