Ladies and Gentlemen:

     This opinion is being furnished in connection with the filing by
Voyager.net, Inc., a Delaware corporation (the "Company"), in connection with
the Company's Registration Statement on Form S-1 (the "Registration Statement"),
filed with the Securities and Exchange Commission pursuant to Rule 462(b) under
the Securities Act of 1933, as amended, relating to 1,293,750 shares of common
stock, par value $.0001 per share ("Common Stock"), of the Company (the
"Shares"). The Shares include 168,750 shares of Common Stock which may be issued
solely to cover over-allotments, if any. All of the Shares are to be sold by the
Company and the Selling Stockholders (as defined in the Underwriting Agreement)
to the several underwriters (the "Underwriters") of which Donaldson, Lufkin &
Jenrette Securities Corporation, First Union Capital Markets Corp., CIBC World
Markets Corp. and DLJdirect, Inc. are the representatives (the
"Representatives") pursuant to an Underwriting Agreement (the "Underwriting
Agreement") entered into between the Company and the Representatives of the
Underwriters.

       In connection with rendering this opinion, we have examined the forms of
the proposed Underwriting Agreement; the Certificate of Incorporation and Bylaws
of the Company, each as amended to date; such records of the corporate
proceedings of the Company as we deemed material; and such other certificates,
receipts, records and documents as we considered necessary for the purposes of
this opinion. In our examination, we have assumed the authenticity of all
documents submitted to us as originals and the conformity with the original
documents of all documents submitted to us as copies.

       We are attorneys admitted to practice in The Commonwealth of
Massachusetts. We express no opinion concerning the laws of any jurisdictions
other than the laws of the United States of America, the laws of The
Commonwealth of Massachusetts and the Delaware General Corporation Law.

     Based on the foregoing and on such legal considerations as we deem
relevant, we are of the opinion that the Shares to be sold by the Company to the
Underwriters as described in the Registration Statement have been duly
authorized under the Delaware General Corporation Law (the "DGCL") and, upon
delivery of such Shares and payment therefor in accordance with the Underwriting
Agreement, will be validly issued, fully paid and non-assessable under the DGCL.

     We hereby consent to the inclusion of this opinion as an exhibit to the
Registration Statement and to the reference to our firm in the Registration
Statement.

                                    Very truly yours,



                                    /s/ Goodwin, Procter & Hoar  LLP
                                    GOODWIN, PROCTER & HOAR  LLP
