Python + Selenium: I can't find an element on my router 'site'

I am trying to write a Python script to automate changing my Wi-Fi password from my router site (10.0.0.2). I'm using Selenium and I have been hitting a brick wall because I can't find some elements. Your help will highly be appreciated. I will provide all necessary resources for debugging below:

I succeeded logging into my router with find element by XPath.

Locates the submit/login button and clicks it:

browser.find_element_by_xpath('//input[@type="submit"]').send_keys(Keys.ENTER)`

Also, I tried several ways to find the element, but I commented them out temporarily.

#Locate Advanced Tab --1
browser.find_element_by_name("Advanced").click()

#Locate Advanced Tab --2
#tt1 = browser.find_element_by_xpath("//td[@id='topnav1']")
#tt1.click()

[1]#Locates the the advance tab on the page -- 3
#adv = browser.find_element_by_id('topnav1')
#adv.send_keys(Keys.RETURN)

This is the code for "Advanced" tab in my router: 

<td id="topnav1" class="topnavoff" width="140"><a       href="javascript:ontopnav('1')">Advanced</a></td>

Edited: Code and error respectively.

browser.find_element_by_link_text("Advanced").click()

Do you have frames on your page? – Ratmir Asanov
@Ratmir Yes, sir. – Originull
@Originull when you say you have frames, did you switch to the exact frame? Post more of outerHTML containing the <frame> tag and your code trial to switch frames. – DebanjanB

To click on the link with text as Advanced you can use any of the following line of code :

  • css_selector :

    browser.find_element_by_css_selector("table#topnav_container2 tr td.topnavoff#topnav1 > a").click()

  • xpath :

    browser.find_element_by_xpath("//table[@id='topnav_container2']//tr//td[@class='topnavoff' and @id='topnav1']/[contains(.,'Advanced')]").click()

Note : The link with text as Advanced is within an <a> tag. Hence you must try to invoke the powerful click() method instead of send_keys(Keys.RETURN) or send_keys(Keys.ENTER) as follows :

browser.find_element_by_link_text("Advanced").click()
