    In fact 2GB for the Home Internet (1 to download and 1 to upload to the mobile) Also routing using a VPN via a home router/network will limit your speed to your home's upload bandwidth, and that's before you take in to account any slow down intorduced by the VPN overheads.

    Basically it's like digging a pipe to your house from wherever you are, the data will need to go down this pipe (your mobile data or whichever WIFI you're connected to) and then will go out from your home router. You'll be limited by the connection speed of whatever connection you are using.

    Your router at home will have to download and upload the data.

    No one can see what's going on inside the pipe, besides your home router.

    Make sense?

    Yeah thanks :) I mostly just use it to putty into my servers I have doing various jobs. Just wanted to check how the streaming side of things would work.

    If you were abroad and wanted to use iPlayer, VPN to home would allow you to do so. @maj

    * Assuming the networks both ends have the bandwidth

    Already tried it and it does as advertised regarding reducing the power drawn and I get a few degrees drop in temperature but it hasn't really helped the USB timing problem (this was one of the things they'd said it should help fix). I've gone back to the original firmware.

    Idle temp in raspbian lite for me is around 60 degrees with no heatsink. Really need a decent case

    Stuck mine in a hacked Rpi3 case and idle temps rose over 60c. Toasty!

    It's now dangling naked behind the tv at 50c.

    Yeah, waiting to really get to grips with my Pi4 for exactly that reason.

    oof! I think I'll hold off for a Pi4 see if I see any info about the heat issues.

    Having seen this, I've ordered the aforementioned fan shim.

    Someone on here that has a 3D printing machine should wack some good ones out for OcUKers, at a cost of course!

    The fan shim from Pimoroni is pretty effective, this is at idle.

    The bigger area low profile heatsinks are also back in stock at Pimoroni as well.

    Applied the Pi4 firmware fix that is supposed to help temperatures last night. Initially didn't notice any differences but after a while I noticed it was idling at around 55 rather than 60 when completely passive with a ~5x10x10mm copper heatsink on it, so a good improvement. Found an old 50mm slim fan in a drawer and re soldered the cables to plug it into the GPIO ports running at 5v and say that on top of the Pi, temperatures dropped to idling at around 35. Sadly the fan is pretty knackered and louder than my main pc :p

    Using it as a desktop via a KVM on my 3440x1440 ultrawide monitor is much better than expected, everything works smoothly than expected. Local/Lan video playback of files is a little clunky in a window, but fine in full screen - opposite behaviour to anything web based via a browser. I hope software improvements come out to make website video playback work, I'm not fussed if it can't do 4k streaming - but I would atleast like solid 1080p Youtube!

    Having upgraded my internet at home, i'm now assessing my options to improve my home network. I have plex running off an old intel core 2 duo PC, which sounds like a plane taking off - not ideal! I also want some way of having an accessible NAS from inside and outside the home, so i can backup and access files from it. Currently I have these on a cheap USB stick and external HDD (an old one!).

    What i was hoping for, was to get a Rasberry Pi 4 with 4gb RAM and use this as a NAS / Plex Server / Music streamer and was wondering if all this was possible?

    I would have one external HDD for plex (a 4TB or so one)

    1 x External HDD for backups (is it possible to have a raid 1 setup to mirror that backup? or if i could mirror that backup to a cloud based service like google drive somewhere?)

    and then music, we have lots of it, i'd like to be able to stream this to a bluetooth speaker if possible.

    Plex would be used by all the family as well as the music.

    I'd like to be able to VNC in, or something along those lines, so i wouldn't need a separate monitor etc. I just want to be able to put the Pi and hard drives in a cupboard, and forget about them but i'd like to be able to download on the Pi, or use the old computer and be able to transfer the files across to the plex external HDD.

    I have read a little, and dabbled in linux but am pretty much a newbie. I prefer using GUI, which i believe is possible with rasbian?

    I hope all of that makes sense and is possible. Any tips or tricks, greatly appreciated. It certainly looks to be a cheaper option than a Synology, plus then buying the drives.

    I think you would grow pretty tired and frustrated with the performance trying to do all of that, you would be be best off with a HP MicroServer or someting with a bit more power to accomplish your goals.

    A Pi would be great to run as a music streamer (plenty of add ons etc avaliable) but as the server for all of that I really wouldn't recommend.

    Thanks mate. I did wonder. Space is at a bit of a premium so thought i'd get away with a Pi. Maybe the HP option is something to look into as well.

    Thank you
