Downloaded Cisco Connect for E1200 v2 disk image damaged. Now what? recent Mountain Lion upgrade

Question

I had originally set up my E1200 Jan 2012 & had Cisco Connect setup. I didn't use it much but back in Oct after being away for 10 days I didn't have internet connection. Had to re-set both cable modem--then I at least had connection via ethernet, but still no wifi connection.  Had to turn off for awhile to get it Router to properly reset & work. & then I think I had to do another reset maybe in Dec, can't remember exactly.
As I mention in another post, I have been having frequent intermittent not connected to internet messages for a long time. Usually if I just turn wifi off & then turn it back on it finds my network (although frequently I notice that it was on my guest network rather than main). I still don't know if it is cable modem, router or my ISP, altho they came out & checked & said signals ok, but modem could be going (Its old but about to move so don't want to buy new modem now).
I updated to Mountain Lion about 2-3 weeks ago.
After a Panic last night I was advised to make sure everything updated including router firmware.
When I opened Cisco Connect it said I had an unsupported Operating System. Trying to figure this all out, I finally found links to download Cisco Connect that are supposed to be compatible w Mountain Lion (at least the original link said that, but not where I went w the links so hoping it is right link for that). Anyway I downloaded it & was reading a bit & then clicket on the setup icon.
That said it was damaged & to eject it. I downloaded it via wifi just like I download other software. Maybe it is hyper sensitive so I need to take it over to plug directly into my cable modem? But then that will mess up the router, although I guess it will need to be reset any way.
So I think i need to get Cisco Connect updated so it works w Mountain Lion. Mountain Lion told me about 1 software that wasn't compatible but didn't pick up on Cisco Connect.
So don't know if I need to do a hard wired download, unlike the way I download other things, or what to get an undamaged copy. I then hope that it will see the old version, even though it isn't didn't work & hopefully pick up all my settings & all.
& then I guess I still need to check for a firmware update. & I understand that a firmware update should be done w a good connection (although the user manual just says good signal, web says hard wired ethernet. & because of the intermittent issues I plan to to it manually by 1st downloading & then installing from the download so there won't be a risk of interruption during install--if its even needed.
I'm running on a mid April 2010 13" MacBookPro
Any suggestions? This all is rather confusing.

Well I was trying to update Cisco Connect so it would work w Mountain Lion but after 3 tries at the download I kept getting this same error message that it is downloaded. I even shut down & restarted before the last time w same result.
I should not have to spend hours of my time to get this to work. That is ridiculous.
Right before starting this process I checked for Apple updates & found a firmware update for my MacBookPro. I quickly downloaded & installed it, no problem. It took a very few minutes & then I backed it up & started working on this many hours ago.
I am an end user--not an IT professional. I just want things to work. I should not be expected to have to spend hours trying to figure out how to get stuff to work & still it doesn't. So I guess Linksys doesn't care that much about making things easy for Mac users.
I recently had the cable co come out & check the levels & all. they all checked out ok & they did change the fittings in several places on the coax connecters for good measure.
My cable modem is set up just across my living room from me & it is not a large living room. The router is right next to it, but it is not at a desk or place that is very comfortable to set up my Mac.
I sure hope that those security settings have been set up by default when I orginally set this up about a year ago. & I don't reall know how to change those settings without Cisco Connect, which I have been unable to get reinstalled since i keep getting those warnings about it being damaged.
I just want my computer devices to work. I don't want to have to spend hours troubleshooting them w poorly written instructions that don't really tell how to update firmware & Cisco Connect for tnose of us who have already had it set up before upgrading to Mountain Lion.
Having a link to download Cisco Connect that supposedly works w Mountain Lion but doesn't since it keeps giving a warning is not very helpful. There was nothing I saw in all my searches to tell what the results of even being able to upgrade Cisco Connect. Would it be able to figure existing settings? Didn't see anything that explained how that would work.
I don't appreciate my time being stolen by making it so hard to just get this updated! I"m giving up on this. I may try taking it back to Best Buy to see if they can tell if the router itself was also defective but I think I will likely go get an airport Express so I have a reliable router that is easy to use!
