Im hoping somebody can help. I have the set of 3 Whole Home Wi-fi discs which give great coverage inside the house. However, outside the house is not so good. I have bought a cheap wireless access point that is single band and I have configured it with the same SSID and password as the 3 discs. I get a strong signal outside now but it as I seem to mostly get a 5 GHz signal inside, I have to wait for this to drop out before I pick up a 2.4 GHz signal outside. So my question is, if I were to buy a non BT dual Chanel WAP , will this work seamlessly with the other discs and will the signal switch seamlessly to a 5Ghz signal when I go outside. I do not want to try and use an add on disc outside, even though it is sheltered from the weather. Any help or advice would be gratefully received. Many thanks.
No, the technology is different. You need a mesh system like the whole home to switch seamlessly. A WAP won't be part of the mesh.
You could try giving the WAP a different SSID, it might switch quicker (might not but worth a try). Is it that critical to have seamless roaming between locations?
