Hello people of android forums! A small bit about myself: I am a programmer and heavy user of linux, both server and client versions. I consider myself very tech savvy with desktops and servers, but I am just now getting used to smartphones. I had been holding out a very long time to buy a phone for myself but people had been bugging me a lot lately so I finally broke down and got my first smartphone, the Nexus 5. It is unlocked with no sim card, which should not be a problem for me because I am only ever at home or school anyway. Anyway, I was having awesome fun setting up the phone at my home wifi, as well as at a friends house. Next I went to school and registered my MAC (they use mac filtering), and it was operational shortly after. Worked fine throughout that day. The next day It still connected correctly, but no data could be had from the internet. (chrome, email, any app, whatever) Network manager claimed that I had full bars. (of wifi) The school network staff claim it is a "known issue with androids", it "never happens with laptops, iphones, or any other type of device". Sadly, I can confirm this after talking to many people, and I also never had any issues connecting my ubuntu thinkpad or asus windows laptop. The network staff also suggested trying "wifi fixer", which I have (both of the top two apps which show up for this search in the play store). No success. Interestingly, I have managed to reluctantly revive the wifi functionality by messing around with the static ip and DNS settings for the connection, but it usually takes 10 minutes or so of messing around and there is no rhyme or reason to it, likely because the school network is not designed to accept static-ips. Strangely, after getting DHCP I notice that the "gateway" and "ip address" do not have the same third number. ( I am no network expert so this might be normal) for example the IP might be 192.168.16.134 while the gateway is 192.168.18.1 when I revive the wifi, it is usually when I return both of these to the same number. Well, that is all of the info I can think of to solve this. tl;dr: wifi connects but no internet. any suggestions anyone has would be much appreciated. Thanks for reading.
