No spacing after Sigma?

There seems to be barely any spacing (if at all) after Sigma, making it hard to read. Is this normal? Is there any way around it? 



 $ Sigma_{v in V} alpha $

    Add your own horizontal space. See What commands are there for horizontal spacing?

    Sigma is a normal greek letter so has no spacing just as abc has no extra spacing, if you mean summation operator then use sum which is a different character and also specified as a math operator so has different spacing.

You should use sum, not Sigma, to create a summation symbol. The sum symbol is slightly larger than Sigma when used in text style, and a whole lot larger when used in display style. In addition, the math type of sum is math-op ("math operator"), whereas the math type of Sigma is math-ord ("ordinary atom"); this strongly affects the amount of whitespace TeX inserts before and after the symbol.

end{document}

Accessing regular linux commands in Huawei's Dopra Linux

Image
4 Backstory: I have a Huawei HG8245 router in my house and I want to change the default username/password. I've tried following this guide but the config file always gets reset. My ISP isn't helping either so I'm looking for other ways to accomplish this. The router has telnet access so this seems like a way to change the credentials. The first shell I gain access to looks like this: WAP> Pressing "?" gives me a list of available commands which I've pasted here, the two interesting ones are "su" and "shell". I can't seem to get su access, even after logging in as root (challenge password prompt, and then nothing happens), but shell gives me a proper linux shell.
