The displayed columns can't be changed on the Lansweeper web console.
However, you could build a custom report, which shows you the data you need for assets in a specific group.
The example report below will list you all assets with Model and MAC address which are in the Group "YourGroup"
Select Top 1000000 tblAssetGroups.AssetGroup As [Asset Group],
tblAssets.AssetID,
tblAssets.AssetName,
tsysAssetTypes.AssetTypename,
tsysAssetTypes.AssetTypeIcon10 As icon,
tblAssetCustom.Model,
tblAssets.Mac,
tblAssets.IPAddress,
tblAssets.Lastseen,
tblAssets.Lasttried
From tblAssets
Inner Join tblAssetCustom On tblAssets.AssetID = tblAssetCustom.AssetID
Inner Join tsysAssetTypes On tsysAssetTypes.AssetType = tblAssets.Assettype
Inner Join tblAssetGroupLink On tblAssets.AssetID = tblAssetGroupLink.AssetID
Inner Join tblAssetGroups On tblAssetGroups.AssetGroupID =
tblAssetGroupLink.AssetGroupID
Where tblAssetGroups.AssetGroup Like '%YourGroup%' And tblAssetCustom.State = 1
Order By [Asset Group],
tblAssets.AssetName
