Can't connect WIFI (wireless), ethernet, LAN, USB can


New Member

please help me, i have a problem with my Laptop that can't connect to my home wifi. Another notebook can connect no problem, handphone and ipod no problem, only this 1 laptop.
I've just bought the laptop, 1 day after that i dont know why become limited, and then after i try many way from google become cannot connect to my wifi. now already 1 week.

I CAN CONNECT to my wifi if i bring the modem wifi really near with my laptop, and sometimes limited, sometimes 'connected' but really super slow connection internet (i tried from my phone the internet connection good)

I have 2 wifi in my home,
1. the Modem wifi and via USB connect to
2. the ROuter TP-LINK

I have tried the third wifi from another person which is same type with my modem wifi, but still can connect. I wonder why.

I have installed the latest drive in hp website. tried changed previous driver, re installed 5 times, whatever way i can find in google, this is the last resort maybe.

These are the descriptions:

: HP 15-r012tx
windows : 8.1 pro WMC 64bit
driver : Ralink RT3290 802.11bgn Wi-Fi Adapter
provider : mediatek
version :
driver date : 8/11/2014
hardware ids: PCI\VEN_1814&DEV_3290&SUBSYS_18EC103C&REV_00

when I connected to ITEZA with superslow connection, i tried the troubleshoot problems, sometimes it says my connection of router is broken, sometimes DNS, sometimes nothing particular.

when i tried repairing the computer via "F9->boot CD->klik repair ->troubleshoot-> check conflict, there is conflic which is "net28x.sys" if I am not mistaken and that is my driver, so i unistall and change the drivers and still no solution

Please can anyone help me? I'd really appreciate it.

If this is a new, 1 week old laptop, I would contact tech support for help. You may have a defective wifi adapter. If it is defective, it should be covered under warranty.
