Hello everybody, I now that this topic has been discussed in other posts, but I had the feeling that every case was some kind of unique (after the usual troubleshooting), so I thought I give it a try with another post. My problem: I live in Spain and moved to a new place, where I am using the same router as before and I contracted the same provider as before (Pepephone, Spain). Due to a company fusion we had to adjust some changes on the router, which we did with Pepephone help-hotline and everything worked out beautifully. We have normal internet connection with my MacBookPro, iPad and iPhone. Now I installed as well my MacPro and I have real trouble getting a decent internet connection or any connection at all, although the WiFi-Signal is all the way up (distance to the router is around 10 meters). I have no download processes in the background that could bring down the speed. Here are the tec specs of my MacPro: OSX El Capitan 10.11.6 MacPro (Mid 2010) Processor 2,8 GHz Quad-Core Intel Xeon Memory 12GB 1066MHz DDR3 ECC Graphics ATI Radeon HD 5770 1024MB Serial No CK10209RHF7 I already tried the following: I did some tests with speedtest.net and the speed varies between the devices. Although the PING is always around 52 I get around 7Mbs download speed with my MacBookPro and only have around 3Mbs with the MacBook. I tried different DNS - 184.108.40.206 - 192.168.1.1 - 192.168.0.1 But did not affect the download speed. Tried to change locations in the Preferences/Network/Wifi-panel. The changing to “Location: Automatic” I do not even get a IP-address and no WiFI signal. I do not have much knowledge about the whole Network stuff, but I was reading the last days in the forums and similar cases. Do you have any suggestions what could be the matter for my slow connection? Thanks a lot!
