I have already read a lot on another topics about this card but haven't find a solution.
I have recently built a new PC on MSI Z87-g45 gaming mobo (bios v1.5). I am using Windows 7 Professional x64. All drivers are installed. I don't have any anty-malware software right now.
At first when using drivers from CD the connection was very poor, loosing a lot of packets and the bandwith was at around ~50kb (It should be 4 Mb).
What have I already done:
- Installing the newest drivers from Asus
- Uninstalling Asus software and using Windows 7 feature instead.
- Uninstalling Asus drivers and installing from realtek site (card is using RTL8192CE) - I am currently using this as they are recommended in another topics.
- I was trying to move card to another PCI-E slots.
In current situation my case is standing under desk in corner and I cannot connect to the router or it does but none of pings are successful.
I can connect and use internet when i move case at the center of my room, but even then ping to the router never goes down below 2ms, mostly it is 3-4ms with jumps to ~30-40ms from time to time and 10% loss. Using Xirrus Wi-Fi Inspector i figured out that under desk the signal strenght is -70 dBm and at the center of the room -68dBm.
For comparison i used my 3year old asus n43jf notebook with Atheros AR9285. Under desk the ping is ~1.5ms on average without any packets lost and signal at -77dBm. At the center it is 1ms with -64dBm.
I don't have physical access to the router although i can log into it. It uses WPA2-PSK / AES. I have tried using different channels without any results.
The router is Zyxel P-2812HNU-F3 with changed (limited) software by the provider.
Is there anything else i can try or i should use my warranty?
