I'm struggling to connect to Wi-Fi... How to download the latest Wi-Fi Drivers

A possible issue can be the driver, we have found that sometimes the wrong driver is installed by Windows.  It reports the card as working but when connecting it either does not connect or drops the connection during use. 

The driver update can be downloaded from: RTLWlanE_WindowsDriver_2024.0.4.208_Drv_3.00.0031_Win10.zip

This downloads as a ZIP file so will need to be extracted.  To perform this right click on the file and click on Extract All, this should then bring up a wizard with “Show extracted file when complete” ticked automatically (if not, please tick this).  Follow the wizard through and when complete you should be presented a series of files, run the Setup application and follow the prompts.

Once this has installed please follow the below which resets your network settings.

Click on Start

Select Settings

Select Network & Internet

Select Network Reset

Select Reset now


If after performing the above you continue to have issues with the wireless please contact us.

Wireless Problems that continue

Systems equipped with a 300Mbps/2.4GHz WiFi card may experience connectivity issues with dual band routers provided by Internet Service Providers.
ISP supplied routers from BT, Plusnet, Virgin and SKY have both 5GHz and 2.4GHz channels enabled automatically.
They will usually have the bands combined by default which can cause connectivity issues.

If your WiFi network shows up as one SSID and not a seperated 2.4GHz and 5GHz channel, it may need to be separated in order to connect a 300Mbps WiFi card reliably.

Please refer to your specific internet router’s documentation on information on how to ‘separate WiFi bands’.

Once you have split the bands on your router, connect to the 2.4GHz WiFi band.

If you are experiencing connectivity issues after this, please follow our guide on how to update your WiFi drivers.

This guidance does not apply to Stormforce Gaming systems featuring high performance 5GHz or WiFi 6 network adapters.

    13 reviews for Onyx RX Vega 11 (Ryzen 5 3400G)

    1. Zippu

      really good for its price can run the games i enjoy and love with ease

    2. John difalo

      i bought this product out of curiosity. Its really good at running my sons favourite game, Apex Legends

    3. Sean Oreilly

      Good solid pc but if you ever want to upgrade graphics bare in mind it only has 350w of power so limited to graphics card you can get

    4. Jayden Roberts

      Ok so I haven’t bought this pc yet but I’m buying it in a few months and I noticed that a different company are charging more for pretty much the same components I can’t write it there so I’m writing it here it’s just so bizarre how there selling the same product with a higher price the only difference between them is the watt this has 350 the other has 450 but when you go on amazon it’s literally 40£ like how Is this allowed I’m just warning people.

    5. Alex Fisher

      I Purchased the same PC last year and it came with a cheap computer case that could fit up to 2 120mm fans (RED LED) in the front. My friend, who paid almost £100 less has a tempered glass side panel that can fit up to 4 120mm fans (RGB) in the front with the same specs. I like Storm Force but they need to get themselves together a little. My friend got better than me and he paid almost £100 less. Overall MY experience is very good with Stromforce and would recommend 100% (if they got things right).

        First of all we would like to thank you for taking the time out to leave a review on our product.
        we would like to take all reviews on board and aim to improve the overall customer experience where we can.

        in regards to the change in chassis, we understand your frustrations. However, some components including chassis do become no longer accessible and we have to change them out and especially during the current global climate, this is not always foreseeable.

        Thank you again for your words and recommendations.

    6. Alex Sanchez

      I am fairly disappointed in this PC, I bought it from argos and on the description of this PC, it said it’s a good PC to get into entry level gaming. However, whenever i try playing Fortnite (which is listed as an entry level game), my frames stay at around 40 and i have most of my graphic settings on the lowest that they can possibly be. I am not happy with this as a £200 Xbox One S is capable of running fortnite at a steady 60FPS whilst having decent graphics. I have tried everything to increase the frame rates but nothing has helped. Overall i am really disappointed and feel like i have wasted my money as the PC is not how it is described.

      What can I say? I’m completely new to this gaming world and was hesitant spending so much money on something I know very little about. I went with stormforce for 3 reasons – 1. Computers are their specialty rather than them just retailing on behalf of someone else. 2 they offer a 3 month warranty and 3. Their reviews were fantastic. I made the right choice, the computer is amazing and my kids are delighted. I only bought the basic model so in future if I wanted to upgrade, I’ll be going back to stormforce.

    8. Joshua

      At first it wouldn’t turn on and had to use a different power cable, but after that in settings I made it so Fortnite (one of the games I play) onto high performance and FPS went high through the roof 20fps too about 150

      Good pc but a lot of fiddling to fix 😀⚡️

    9. Stephanie Piercy

      My son loves this PC. He plays all his games like Fortnite and roblox on it. Excellent Christmas gift .

    10. Armand Baker

      Good gaming pc if ur not to serious about gaming, can run certain games really well would recommend to many people I will be choosing storm force in the future

    11. Samzy

      If only this was priced at £500 on the dot, and had better specs, this would be a 5 star from me but the main thing is for the people who are planning to buy this product, the Stock Cooler is Chinese (Made in China) and isn’t good at all, and the Motherboard can be better.

    12. Anonymous

      I haven’t bought this pc yet but i want to buy it from argos but from one review i read here they said they wouldn’t recommend buying from there but i dont know if i should buy it straight from here or argos because on the argos page they say the pc (which is the same as this one) is cheaper and better it has 3.7 ghz which i dont know if it is true so can anyone tell me to buy from here or on argos.

    13. Aaronjon@hotmail.co.uk

      I don’t ever write reviews but felt this deserved one based on my experience, Amazing PC, for basic gaming and schoolwork for the kids but pretty much plays all the big named games, if your a hardcore gamer then best to upgrade slightly but I think this works for my needs, I bought this through Argos but had an issue with the wireless card, contacted customer support who were outstanding, amazing and brilliant sorted the issue out super fast, no issues no hassle very rare to see how well they handled my enquiry so I’m writing this review just for that reason, wireless card upgraded and replaced within a week I will definitely use storm force again (and recommend them) for all my future needs. thankyou very much.
