How does kudos network work?

kudos network uses a clever form of Internet business. first you sign up (give them your email address etc.) then they will have to accept one of the offers given by the website. all of the offers are fantastic and safe but I personally used 'lumosity' which is a brain improvement site, just click proceed to lumosity and sign up for the FREE 14 day trial and play just one of the brain games. after you have played one of the games your lumosity username will be displayed in the top right corner of the page, click on it and it will bring down a drop down, click account, then click cancel continuation (or something like that) which means after the 14 day free trial your account will be cancelled from the site and you wont pay. however, you can carry on and pay for the site which i would recommend as it really improves your brain function. after you have done this go back on to your kudos account in about 4 hours and it'll have registered that you have completed the offer. after this you can start getting referrals which lead to free gifts! each time somebody completes an offer kudos networks get a comission from whichever company it was completed with. each time a referral is completed the get another commision. the money from the offer and the required number of the referrals for the product kudos networks make a profit (deserved profit) so everybody is a winner. you get a referral code which you need to post on forums or email it, be creative! kudos is 100% safe and amazing! get started today, click on the link below(my referral code, help me out?:D)

Do you need a certain wireless router to use gvtc wifi service?

You can use your own but you have to call GVTC to get it set up. If you change your own router with another one it will not work until you call tech support. I haven't ever seen a provider like this before. When we want to network a DVR (Digital Video Recorder) for camera systems we can't login to the router and open ports on our own. We have to call their tech support and give them the public ip so they can open the ports we need opened. It's a gift and a curse. When it works the first time it's awesome, when it doesn't it sucks. We just had to beg a tech to look further into our cameras not coming up, he finally did and saw a setting was wrong. Fixed it and all was good, but at first he said everything was correct and that it was something on our end... sorry to ramble but just know you have to call tech for any new router or router swap.
