deco M4 and iOS internet issue
I am facing issue with iOS12 iPad, some apps like Facebook work and some webpages in safari open, app store opens and shows download page but cant download, YouTube app shows no internet, it was working till few days back without any issue, thought it was something to do with some update for ipad but it isn't as it work fine with tp-link archer C7 router and other wifi connections include mobile hotspot(9-11Mbps connection). Older iPad with iOS6.5 work fine , all other deices like android phones , laptops even Microsoft surface , and TV work fine , even the speed is 50 to 75 Mbps so speed is not a issue as well. I have factory reset the ipad and even re did the deco set up, but I have same issue.
I am using deco as Access point . also checked by switching off other decos and keeping only the main Deco ON, still there is no change.
