        @edmaul69 i can connect to winscp using the ip adress of the pi instead of the username?, everytime i cant connect to winscp it says username does not exist and thats when i have to unplug and plug back the router to get it to work again, when im connected to my wiscp it says pi@RETROPIE

          @nestor1924 instead of host name as retropie or whatever use the ip address. user name is still pi

            @nestor1924 Does @Alturis' screenshot match your Winscp window? Instead of "retropie" in the "Host:" field, you would simply enter the IP that Retropie shows you. Beware that the IP might change if you reboot the pi or after losing the connection.

            Alternatively, you could give your Pi a static ip address in your router. This site tells you how to find your router's address and log into its web interface (or "Admin Tool" as Technicolor calls it). You can also download the TC8715D's manual there. On page 64, it tells you how to give a "reserved" (i.e. static) IP address to a connected device, such as your Pi. You should use one of the IPs your Pi had before, as the chances are good that those IPs are not used by other devices. To be sure, look at the list of connected devices in the router's web interface to check their IPs.

            However, static IPs should be the last resort in an otherwise dynamic network. If looking up your Pi's IP in Emulation Station does the job for you, stay with it.

              Care to explain why? I've never heard anyone else say that. I'm also having some networking issues on my RP setup. But I do use dhcp reservation on my wndr4500 to get static IPs, so your comment has me thinking maybe that is my problem.

                @creativename You got me there, thanks. I muddled static with reserved ips, although they're different things. (Someone may correct me if I err again.) To my knowledge, static ips are configured on the devices themselves, whereas reserved ips are part of the dynamic DHCP process, just reserved for particular devices.

                I heard many times that static ips in an otherwise dynamic ip address space may collide with dynamic ips given by the DHCP server, thus they should be avoided or the whole network should be set to static ips. In @nestor1924's case, this doesn't apply, as the ip would be reserved, not static.

                edit: The method of assigning ips doesn't affect ssh on your system, so DHCP reservation shouldn't matter at all for your ssh problem. I can't say anything about your Windows problem because I don't use Windows.

                  Actually, duplicate IP are bad, but you can set a DHCP range on a subnet to mix static and dynamic IP.
                  For example, on 192.168.0.0/24, you can set your DHCP range to 192.168.0.100-192.168.0.200 and use the rest of the subnet for static IP.
                  But this require minimal network knowledge and some strictness in network management.

                  That's why generally advised solutions are to avoid this, either by not mixing static/dynamic, or by using dynamic with reserved IP.
                  My 2 cents.

                    @nestor1924 on the retropie can you go into retropie menu and then show ip and verify that the ip address matches the one on your winscp?

                    What is the reasoning behind this? Why are people recommending that he use the IP instead of "retropie" ?

                      Because sometimes it won't recognise the hostname but it will recognise the IP.

                        I managed to change the serting of the pi to reserved ip and had no issiues "yet" if it returns ill let you guys know, i still connect to winscp via the username, if the issue returns ill use the ip of the pi on winscp as the username to see what happens...
