Hello all, thanks for the help this forum has provided me.
I come from the spyware forums after a trip there.
I wonder if you guys can guide me a little here.
For some time (I don't know how much, I just noticed it a year ago) the signal on my laptop (HP) goes straight down and overall speed of it is awful.
I thought it might have to do with virus but the problem still persist after a good cleaning.
Here's what I know so far:
-In wifi status the signal goes down completely and speed falls to 144Kbps (when it's full it says 72Mbps)
-This happens from time to time, at least 6 or 7 times in 10 minutes with no fixed intervals but lasts somewhere between a couple of seconds and 20 seconds.
-Sometimes it stays at 5.5Mbps with a good signal, this is fixed by disabling and reenabling the wifi device.
-Download speeds (tested on google drive) can go from 5Mbps to 60Kbps. Speedtest hit 30Mbps tops in a good day, in a bad one it's 5Mbps at most.
-This only happens on this computer. My partner computer (right beside mine) has a similar network card (Also a Broadcom but on an Asus laptop) but never had this problem (and it's the default driver); my sister has a newer laptop but her speed says 866,7Mbps.
-My computer and my partner's are at about 2-3 meters away from the modem/router; my sister's is at least 4 or 5 meters and 2 rooms away.
-I doubt my ISP or router has something to do with this since every other device works excelent (smartTV, phones and computers)
-I also doubt it has to do with how many device are connected since I tried flushing every device and just connecting this one.
-There are no obstacles between it and my computer (only a deodorant but it's free range otherwise, no electronics near it)
-Surfing the net looking for an answer I found that a lot of people had this problem (Broadcom BCM43142 802.11 bgn Wi-Fi M.2 Adapter) and several people fixed it by updating the drivers. Mine are updated, problem persist.
-I ran Xirrus analyzer sometime ago: Signal is excelent overall (between -35 and -55 all the time, except when it goes off at -85 -90), it's currently in channel 6 (the overall best) and I live in an area with few signals around me.
-I cleaned up dust a month and half ago, didn't saw a physical problem on it.
-Ethernet cable also works awful with the same periodic disconnections and slow speed (somewhere around 500Mbps, other computer shows 1Gbps)
Other than that I don't know what else to tell you.
What I'm wondering is if anyone knows if this can be fixed/knows anything or should I straight up get a usb adapter or something. There's no official support where I live so they ship it away for a couple of months and it's way too expensive.
And if so, what would you recommend for a 3rd world budget?
Thank you all once again for your time and help.
Sorry about the lengthy post
