Help! Being told 2 different things from CSR and need more info to make best choice.

Hello all..I'm a lakebum. Currently a Gen 4 customer with HT1100 modem and getting ready to upgrade to the new Gen 5. I've made a couple of call to CS seeking info on the options available. 1st told that I could buy (not into leasing) the new modem for $200 and that I would be able to diable wifi as I wish to use my router..with free dish re-alignment. 2nd time I call was told the new modem and dish re-aligment would cost $326 (reg.$426 -$100 discount for already being a customer) and that I couldn't disable wifi. Was also told that I could keep using my HT1100 modem (starting April 1st) if I wish and would just need to have my dish re-aligned.

My questions are...

Does any one know the pricing of new modem and dish re-alignment?

Will my HT1100 modem work with Gen 5?

If my current modem will work with Gen5..other than the wifi feature..is there any other benfits to switch to the new modem?

Can wifi be disabled on the new modem being offered? (I read the user manual and think it can be turned off but they said no)

Thanks and any help would be appreciated
