Notebook drops wifi connection randomly- Ralink network card

Hi,

My computer has recently started to drop the WiFi connection, reconnect after a while and at times, not even detect my WiFi connection for a while. Then repeats the process for no apparent reason, I'm not sure when exactly thus problem started as I had been using Ethernet cable up until last week. I am certain that this is not related to my router as 3-4 other devices in my house can access the internet perfectly fine.

I have tried doing a power cycle of the router, restarting the notebook, re-installing/updating drivers and cmd ipocnfig /refresh (and other commands along those lines)

My notebook model is the hp pavilion 3132tx- windows 7 64bit, intel I7, 8gb ram and uses a ralink RT3090 network card.

Ps: the problem appears to be alright if I use older versions of the driver (have tried 3.1.18.0 and the default one which came with the notebook [which is older than it]) however, I would prefer not to have to use the older versions as task manager says that its link speed is only 39 mbps whereas versions 5.0.5.0+ would show 79 mbps

Thankyou in advance.
