Re: Raspberry pi is unable to reach Gateway

Re: wifi issues

so after the usb extension is plugged in, my iwconfig is displaying the exact same information with no extender. This should rule out RF interference, I suspect it is something else. what settings can I look at to see if that will do the trick? I would suggest that the user is the problem. and it i...

Re: keyboard layout does not change

When you change the keyboard you make a change in the configuration stored on the SD card. If this change disappears after a reboot then it may well be possible that the card is faulty and your configuration change was not written permanently to the card.

Re: keyboard layout does not change

I suggest that you replace SD card, it is not unusual for SD cards to go into a read-only state when faulty. The symptoms are that the card accept writes but after power off this information has disappeared. What you could do is to create a file with some text in the home directory and see if this e...

Re: Got a PI Zero! want wifi

I doubt a Zero can provide enough juice to run a keyboard, mouse and wifi without a powered hub, I tried mine with the above plus a bluetooth dongle on an unpowered hub, and it couldnt cope. OK with mouse and keyboard though. Maybe it would have worked with a better power supply ? AFAIK The power f...

Re: NAS WiFi speed

I made a wired connection between RPi3 and router wishing better transfer speeds, but it did NOT change. Still 10~15Mbit/s. Now my setup is: http://i.imgur.com/hTArZhS.jpg Link for larger image: http://imgur.com/a/BHwyO Shouldn't this be better? There must be a way to make it better without having ...

Re: NAS WiFi speed

It seems too slow. I have some good news and some bad news. The good news is that you are getting a reasonable throughput considering that there are two WiFi connections involved. The bad news is that you may not be able to improve the throughput because it is very like due too the quality of the W...

Re: Setting up Pi with only Ethernet Cable and Desktop

Instead of messing with dhcp on windows, you could just set the windows nic to a static ip E.g 192.168.1.100 Then set the pi ip to 192.168.1.200 I can not recommend this. Theoretically you can dig into Windows and assign a fixed address but preferably not 192.168.0.x or 192.192.168.1.x because this...

There are many factors that will influence the transfer of data over a network.

Re: NAS WiFi speed

Ok now I've got 15Mbit/s by changing the wireless channel; it seems like a joke. I thought it could be a problem with data flowing from RPi3 to External HDD, but since it's a USB 2.0 connection (about 480Mbit/s) it shouldn't be a bottleneck. Sometimes it helps to draw a picture with all the compone...

Re: Setting up Pi with only Ethernet Cable and Desktop

So this worked. However, every time the NIC is restarted, the subnet changes! So this isn't a premature solution. I'll have to fiddle with Windows' DHCP server to make sure it's handing out addresses and also find what IP addresses were handed out. There a few misunderstandings here. The subnet doe...

Re: NAS WiFi speed

You should always use a cable to connect a NAS to a switch because the cable is a direct, dedicated, connection. WiFi is a shared medium, all the clients share the frequencies and performance varies depending on distance and interferences from other WiFi devices. Your NAS is the central application ...

Re: Setting up Pi with only Ethernet Cable and Desktop

Do you have a gigabit ethernet adapter in your desktop ? How many wires are connected in your ethernet cable ? If there are only 4 wires then you may need a "crossover" cable, if there are 8 wires then the cable might be faulty. A direct connection using a PC with a 100Mbit network card using an 8-c...
