on the good side , when it work , the basic internet connectivity work fine . I have have it for half a year now connect with Comcast , and never have any connectivity issue -lrb- unlike the comcast-provided basic Motorola modem -rrb- . on the bad side , it be the third unit by now . I have buy it at BestBuy , and they have be replace they without any question by just stop at the store . good luck shipping it back and forth if you buy it online . the first one have the cable connectivity and ethernet work fine but the WiFi just be not there , be not even show in the config menu . I have call the support and they have say to replace the unit , so I do . the second unit work fine for half a year until it die . there be a big thunderstorm on that day , which might be relate . it be be connect though a UPS _ and _ a surge protector , so the power line can not be the issue . and I have have a laptop sit next to it , plug directly into the wall , connect to WiFi . no problem with the laptop , the router be dead . perhaps it do not have the adequate protection on the antenna circuit . so now I have the third unit , again replace by warranty , and so far it work fine again . the other bad news be that it be quite feature-poor . no comparison at all to the router that Verizon provide with fio -lrb- and mind you , at no charge , unlike Comcast -rrb- . it can not do static address in the lan -lrb- you can leave a block for static address in dhcp but you can not hardcode fixed address in dhcp -rrb- . it can not do the local dn domain for the LAN . you can not assign symbolic name name nor fixed address to you dhcped machine . so if you have say a networked printer , reach it become not exactly straightforward .
