Link Att wifi bill with Direct stream bill

it's not. Changed hands months ago. So different payment system.

DirecTV and AT&T are now different companies with different billing systems. 

Did I miss something on this? It used to be DirecTV and AT&T were different companies, and then AT&T bought or merged with DirecTV and now it's changed yet again?

Yes, it changed. Last year AT&T spun off DirecTV to a separate company. 

att and directv are still together in a sense...the att tv/att now/uverse, etc., are being switched over the dtv streaming when possible BUT loyalty/retention agents (ask for that dept) with ATT and DTV should be able to access both ATT and DTV accts including internet, satellite, streaming, uverse, and home phone. hope this helps...

Accessing accounts is different than combining accounts. I'm pretty sure they no longer combine AT&T and DirecTV accounts as the systems are being separated.

streaming is the only acct that cannot be combined with any other acct at this time. dtv satellite can possibly be put on the same combined bill as att services but it is actually on a case by case basis as to whether or not the computer system lets this happen.
