No issues so far.
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I've had many modems before this one that were terrible, especially those AT&T modems. I would have to do my daily modem reboot just so the family could access the internet. So far I've had no issues, nor had to reboot this device for any reason since I set up over a month ago.
