How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
for /f "tokens=2 delims=:" %%r in ('netsh wlan show interface name=WiFi^|findstr "Channel"') do Set Channel=%%rThis will leave a space before the %%r but you shouldn't need to trim it for your use. Add aecho "%Channel%"to see the results. I could write this whole batch file for you but I HIGHLY suggest that you take the tidbit I gave you and solve the rest. Useif /?to figure out the greater than and less than logic.
