Hi @Sharona2010,
Thank you for posting here in the Roku Community!
We understand you're having a problem with the channels on Roku since it was crashing. We're happy to assist you further. How far is your Roku device from your network router? Did we recently make any changes to your network or network provider? Do you have cellular data, so we can try connecting your device to your hotspot?
We look forward to hearing from you soon.
Thanks,
John
