We have a big 5 bedroom home which had issues with Wireless due to the distance between our router to all our rooms. Sid came in and found a solution by first having a look at the capabilities of our router and mentioned dual band 2.4/5GHz. On his first visit he installed wireless dual band range extenders in our hallway and now we no longer have any dead spots in our WiFi. Very honest and a genuinely good honest person that does not charge and arm and a leg to get the job done. He also told us how we could improve the WIFI even further by upgrading our laptops to the newer 5GHZ frequency so that it is aligned with technology built into our router.
