The login page only comes up if I connect through a wifi router then it will show up as fast as posiible. but when i am connecting a cable to direct to a windows pc with a local ip assining to it . it reaches to host but there will no login page and also tried bypassing the local ip but it remains same but using wifi router it works fine…please help me regarding this…and sorry for my english
