    Im having hell of a trouble getting a good wifi speed on my computer using a usb wifi dongle, where my phone and tablet gets 50mbps every time but my pc is hit and miss sometimes 30-40mbps

    Most likely the USB wifi dongle is of a low spec, such as 802.11a/b/g/n standard only. What make & model is it? If you want better wifi speeds then you may need to upgrade it. If you have a desktop PC with a spare PCI express slot then consider a PCI wifi card - IMHO they are far better than USB based wifi adaptors for speeds/performance but without the portability of course. Something like this or this would do a great job. I have the latter and it works flawlessly :)

    It's a TP-Link WN722N.

    The reason i'm puzzled why i'm getting slow wifi speeds on my PC is because I get far better speeds on my Android Tablet.

    It's like something is blocking the signal on my PC but not my Tablet. I would of thought my Tablet would be just as bad or worse?

    This morning my speed is:

    Tablet 54mbps

    PC 26mbps

    Sometimes my PC will get to speeds of 54mbs other times it wont which makes me think something is blocking the signal.

    Agreed. A PCI card is likely to be better than a USB dongle. That would be my first suggestion.

    For intermittent speed issues you could also have interference from other devices, microwaves, etc. Try a Wi-Fi signal scanner app to see if there are other signals on the same channel as your router. You should also be able to see any localised signal dropouts.

    Thanks. That model isn't even 802.11n wifi standard...its only 802.11b/g. Your Android tablet will at least have a 802.11n wifi radio hence why you get better speeds on that. Nothing to do anything blocking the signal on your PC. As I suggested earlier, try to get a PCI wifi card for your PC (if compatible) otherwise if you want to stick with a USB wifi adaptor then I recommend something like this.

    Great I just quickly went out and got one so didn't bother looking into what I needed:facepalm:
    I split up with someone so I had to move into a shared house so thought I would quickly buy a usb one without thinking about it, I'm hoping this will be short term.

    Cheers Guys:):smashin:

    By the looks of it, the max speed is 150mbps.
    Newer n WiFi have speeds of up to 800mbps

    900Mbps actually, but the higher ratings are poorly supported modes so your router may not support them.

    I'd expect most recentish routers to support 2 or 3 streams at 40Mhz bandwidth at 5Ghz.

    But yes, it is a low end model only supporting 1 stream and 2.4Ghz, as well as being an older chip, could well explain the speeds. You don't mention the age or model of your tablet so I can't check but it is plausible that it's more capable.

    Apologies, I was looking at TP-Link WN722N-V1 which is b/g only but the V3 also has 802.11n so I'm guessing you have that model. TBH there's far better wifi adaptors (both USB & PCI) so if you can, return it for a full refund and get one of the previous ones i mentioned, PCI express if possible.

    Think I might return it then cheers, I have noticed one thing that made me think its something to do with my computer, When I boot up my pc I get good high speed results then after about 5 minutes it slows down so if I unplug the wifi dongle and put it straight back in I get good results again but then after 5 minutes it slows down, I have checked in the bios to make sure the usb ports weren't going into sleep mode or similar.

    Does the TP-Link WN722N work on the 5ghz band? I'm not connected to 5ghz.

    According to the specs here, its only a single band 2.4ghz adaptor, ie doesn't support anything above 802.11n wifi standard. 802.11ac is a mature/well established wifi technology so you will need to buy a dual band wifi adaptor. See my earlier suggestions, all of which support 802.11ac wifi and are dual band (2.4ghz & 5ghz).

    So this maybe why my speed is good on my Samsung Tab A 2017 model its using the 5ghz. Where my pc is only 2.4ghz

    How do I tell when my device ie Tablet is using 5ghz? I just want to make sure its using 5ghz before I buy a usb one for my pc.

    Assuming your router is dual band 802.11ac then look in the router settings to see which band your samsung tablet is connected to. Alternatively, download a free app such as 'wi-fi sweetspots' on your tablet and run a test whilst standing next to your router. If the app shows the link speed as > 433 Mbps then your tablet will almost certainly be using 802.11ac on the 5ghz band.

    I'm temporary living in a shared house which is run by the council so the router is locked away in a room where I have no idea where it is, So I have no access to it. Its a big house with Fortinet APs on each floor level there is one right near my bedroom door.

    I shall have a go with a app.

    Your link speed is showing around 94 Mb/s which might suggest you're connected to a 802.11n network, even if you're connected to the 5ghz band (802.11n works on both bands). I'm guessing you're not able to access the wifi access point and change its settings if necessary?

    O Right :thumbsdow No I'm not able to get access to the access point let alone change anything, maybe best to get a dual band wifi adapter and see how it goes.

    I now have speeds of 50-57 Mbps using a dual band wifi card, ASUS PCE-AC55BT:):lesson: Shame about the upload being slower than a snail. Nothing I can do with that though :(
