EXHIBIT 5.1

                         OPINION AND CONSENT OF COUNSEL


May 25, 2007

ERF Wireless, Inc.

Ladies and Gentlemen:

We have examined the registration statement on Form S-8 of ERF Wireless, Inc., a
Nevada  corporation  (the  "Registrant"),  to be filed with the  Securities  and
Exchange Commission (the "Registration Statement"), relating to the registration
under  the  Securities  Act of 1933,  as  amended,  of  5,000,000  shares of the
Registrant's common stock, $.001 par value per share (the "Common Stock"), under
the plan described in the Registration Statement (the "Plan").

As your  counsel in  connection  with this  transaction,  we have  examined  the
proceedings taken and are familiar with the proceedings  proposed to be taken by
you in connection with the issuance and sale of the Common Stock pursuant to the
Plan.

We are of the opinion that the shares of Common  Stock,  when issued and sold in
the manner  described in the  Registration  Statement and the exhibits  thereto,
will be legally and validly issued, fully-paid and non-assessable.

We  consent  to the  use of  this  opinion  as an  exhibit  to the  Registration
Statement  and  further  consent  to all  references  to us in the  Registration
Statement and any amendments thereto.


                                                     Very truly yours,


                                                     /s/ Brewer & Pritchard, PC
