![]() ![]() Compared to WiFi card in older laptop (Dell 1555), this Ralink card in newer laptop (HP4540s) handles weaker WiFi signal much worse.Ģ. Ralink WiFi card doesn't use 812.11n signal and it is stuck at 54MBps.Ģ. This is something I've never had to do with my Dell studio 1555.ġ. I need to turn-off and then turn-on again WiFi card in order to take advantage of better signal. But when signal strength increase back to 4 bars, download speed doesn't follow this and stays at same low rate of 30-40Kbps. ![]() At that moment download speed decreases to 30-40Kbps. When I start to downloading something and, let say, download speed is 400Kbps - sometimes wireless signal strength in Win7 indicator drops from 4 to 3 bars (indicating degradation of wifi signal). Despite router working in n mode (300Mbps), Ralink WiFi card is reporting only 54Mbps speed. Situation with signal improved slightly, less complex web pages are loading ok, but YouTube still doesn't work smoothly (constant freezes). I borrowed another router form my friend (Tenda W308R 812.11b/g/n 200Mbps). YouTube is useless with often interruptions of video stream even on lowest quality. There are constant oscillations in signal quality and speed. However, with HP 4540s Internet browsing become very tedious business.

I was able to open web pages and watch YouTube videos smoothly on 360p and 720p. In the room where I usually use laptop (router is in another room some 8-10m away) signal is not best one but my old Dell Studio 1555 never had any obvious problem with it. I first started with my old D-Link DIR300 router which works in 812.11g mode. Last night I tested Ralink WiFi more thoroughly in my home. I also wouldn't like to see this thread closed as I'm not in position to return laptop. ![]()
