    Does WiFi signal strength effect internet speed?

    ...and by how much?

    I recently moved my Wireless router to another room in my house. There is now 2 walls and a fridge between the router and where I normally use my laptop.

    My signal strength has gone from "Excellent" (or 100% on my widget) to "Low" (or 70% on my widget).

    My internet speed seems quite a bit slower, however my internet speed has always seemed to fluctuate quite a bit, so I am not sure if it is related (I just moved the router a couple hours ago).

    So will low signal strength effect my internet speed? By a lot?

    well im not sure specificallywhat happens i can tell you that it shouldnt

    affect your internet speed because you will never reach full bandwidth

    (54Mbps, 108Mbps) but it will affect streaming of files across your network,

    (music,videos) you can tell by the icon in lower right corner, usually the

    speed will lower because of the lower signal strength. i would say move

    the router back, but if you cant maybee look into an extended range, or

    mimo router. or even try moving your laptop a few feet sometimes you can

    catch a wave that way. hope this helps

    Ok, cool thats good to know. I don't stream much between my 2 computers, mostly only documents (excel, word, etc.), so that's not much of an issue.

    Thanks for the info guys.

    I don't think it should affect it that much. Lower signal strength just means you are meeting a certain level, similar to your cell phone. Whether you have 5 bars or 2 bars, it still works, right?. After all, with digital you either have the packet or you don't. The only downside to a lower signal meter is possible it being more suseptible to interference and possibly might lose more packets in transit, which would cause the need for retransmission, so that might be what makes it slower.

    On my G setup, the WiFi connection speed changes depending on the quality of connection (according to the software).

    The connection speed varies according to signal strength. For my dlink card, full bars gives me 52.5mbps, and goes down as far as 5mbps at its weakest.
    So depending on signal strength you can notice the difference just web browsing.

    Tell you what...It is advised not to have microwave oven or cell phone put close to the wireless router. this is because the router should be operating at 2.4Ghz frequency so the signal might be disrupted by the use of the microwave oven or cell phone.

    internet speed will always be slower over wireless no matter how close you are comparing it to plugging it into the router (i dont know why, but it just is. The internet speed itself shouldnt fluctuate much unless you have cable or share a line, but if your connection speed on wifi exceeds your internet connection then it shouldnt be too bad
