You can renew with EAD. I've been renewing my license in DFW area for 8 years now. Take your passport, EAD and I-94 if u have. Here are couple of scenarios that happened to me/wife.
1. EAD valid - License renewed till expiration of EAD, around 2 years, since my EAD was renewed each time for 2 years.
2. EAD expired, but didn't take I94 to the DPS - Lewisville DPS checked online for I94 and triggered a secondary verification, got a letter that I can go back to the DPS with that letter to renew my license. Got a 1 yr extension.
3. EAD expired, took I94 to DPS - Carrolton DPS looked at I94, passport and EAD, triggered a secondary verification, then after receiving letter, got 1 yr extension.
Just in case wondering, my last 2 EAD renewals took 5-6 months, and i applied 4 months earlier.
