I've got a Samsung Series 3 11.6" laptop (NP300U1A) and I just upgraded the HDD to a Samsung 840, non-pro.
I used the Samsung migrating software and everything seems to have worked flawlessly, except for the wireless internet.
At first, the internet lagged horribly, and now the speed generally seems to be okay (sometimes spotty), but out of the blue I will get disconnected and see that red X in the bottom right corner, as if I had no wireless adapter installed. I'd either have to restart or put the computer on sleep and wake it up.
I've updated the drivers and everything else works great. Any guesses on what the culprit could be? Appreciate the help!
Sorry, correction to the original post. The red X isn't the same as if I had no adapter installed. It is the one that shows the signal bars, with an X over it, and says "not connected, no connections are available." I've uninstalled and reinstalled the driver a few times but unfortunately, it hasn't changed the situation.
Also, the disconnections seem to happen when I download large files using more bandwidth.
Okay you may be right, it might be a hardware issue. I plugged in my wireless adapter from my desktop and low and behold, the speed is blazing fast. 30+ megs vs 1ish. I'm gonna open up the laptop again...any idea where I should be looking and what it looks like?
Alright well as of now it seems to be a reception issue. If i take my laptop into the next room with the wireless router and cable modem, the connection is fine. If I bring it back to my room, the bars may or may not drop, but the speed is ridiculously slow regardless.
Thing is, I've kept it at the same place in my room since day one and reception and speed have been fine. It only changed since the SSD install. Could I have tampered with something during the installation? I checked the adapter, wires coming out of it, and the metal plate that seems to be the antenna in the laptop case and things seem to be normal. Why would the reception get so weak all of the sudden?
So desperate times call for desperate measures. I decided to experiment by wrapping a piece of heavy duty aluminum foil around the metal wireless "antenna" inside the laptop and guess what...things are back to normal again.
My suspicion is that the issue had to do with some sort of interference that the SSD was giving the antenna, as the connection to the SSD was located directly next to the antenna, almost touching. But that's just my guess. I'd still like to hear some theories from some more knowledgeable folks out there though...
