I appreciate the help but I believe the R9 390 is a dual bios, it isn't really a clock speed problem just a black screen whenever the drivers are installed so in theory a bios flash should fix this

Hey there so the title pretty much says it all really as im trying to find a way to reflash the bios on this Sapphire Nitro R9 390 Tri X so if anyone can tell me what i should do that would be great

anyone? also i tried a ethernet cable still same speeds

yeah thats what im trying to say? sorry if i didnt make it clear im trying to figure out why my desktop is suffering bad download speeds over WifI

nope, I tried the ethernet connection from my desktop (the one with the internet problems) and into my old laptop (which the internet on it's fine)

but other devices on my network are getting different speeds, I've reset the modem same speeds

@Minibois

done all of that

ill upload the image again

I've tried wired through one of my old laptops with wireless connection same speeds

so as the title states I'm currently having some internet problems, for example my Wifi connection is currently fluctuating between 1mbps download and 20 Mbps (as shown in the picture below) ive tried everything from switching adapters on my computers to switching channels on the modem but nothing is working So if anyone could give me any advice that would be great

Alright Thx Everyone

but like my ISP is compatible with anything far as i know...

so is there any possible way i can build my own modem?
