I live in Austria, where ADSL connections are of the type Annex-A.
As I understand, an ADSL modem has to match the Annex Type of the local infrastructure in order for it to work properly. For instance a Annex-B modem would not work with Annex-A infrastructure.
My existing modem-router provided by the phone company is about 6 years old. I’m thinking of using this existing modem-router, disabling its onboard wlan, and pairing it with a new router that supports better wlan speeds. So basically, I will be looking for a wireless access point and not a new modem.
At what point does Annex Type become irrelevant in selecting hardware? For instance, as far as I understand, if I were to use an ethernet switch behind my existing modem-router, it wouldn’t matter what Annex were in place.
When selecting a wlan router that will be used only as an wireless access point, do I have to ensure that the wlan router matches the Annex Type of the internet connection? Or is it irrelevant?
