Wired or Wireless DSL is slow. The more you put on it the slower it gets. AND when I say more Im also talking about your neighbors. Ad free Speed test will show huge latency and very poor speed because its DSL. [URL] My Wireless speeds are 10X faster than wired 10 meg ethernet.   DSL 1536/512 kbit/s MAX theoretical speed. But I have FIOS and Tri Band 802.11AC router.

I have two Inspiron desktops in the same room, on the same network, both wired.  The older one gets good speeds around 30 both on wifi and ethernet (my max is 36) but the new one cannot get above 10 on ethernet and 2 on wifi, this is when nothing else at all is connected to the wifi  just this pc.   Everything is identical, something on this new one is throttling my speed. I know about Smartbyte but cannot see that installed.
