If you haven’t seen the update on your own device it’s possible to grab the necessary file from the buttons below both in a Full ROM version and just as a link to the OTA file that will update you from v4.5.4 to v4.5.5. In addition to the improvements made to the Wi-Fi connectivity the update also brings along some fixes for things like the Wi-Fi signal displaying as being weak on a consistent basis. Users currently experiencing this particular problem should see it disappear after installing this latest update to OxygenOS, though it should be kept in mind that this is OxygenOS meant for the OnePlus 5 and not for past OnePlus devices. This update also quickly follows the one that was sent out back on June 28th that bumped users up to OxygenOS v4.5.3.
