An IP address conflict occurs when two devices try to use the same address on one local network. Connectivity can become intermittent or fail for either device, sometimes depending on which wakes first. Inspect router leases, reservations and manually assigned addresses before blaming the stream. Use the intended DHCP arrangement or a documented reservation rather than picking another random address. Correcting the conflict should be followed by renewed connections and a repeat of the original playback test on the affected device.
Look for a shared-address pattern
Check whether trouble begins when another known device powers on or reconnects. Router logs or device messages may identify duplicate-address detection, though not every system exposes it. Record both devices and their network details privately. A television that works until a printer wakes could have a local addressing problem rather than an evening server outage. Do not infer a conflict from one freeze alone; establish whether the same address is actually assigned or configured on more than one active device.
Compare manual settings with the DHCP pool
A manually configured address inside the router allocation range can later be offered to another client if it was not reserved or excluded correctly. Inspect the router documented reservation mechanism and any second device serving DHCP. Do not remove leases indiscriminately or assign a guessed address outside the subnet. Correct the configuration at its source. On networks you do not administer, provide the observations to the operator instead of changing another person device settings or trying to claim an address for yourself.
Renew and verify both devices
After correcting the assignment plan, reconnect or renew the affected clients through supported controls so they receive valid distinct configuration. Confirm their local and internet access, then watch the original programme while the other device is also active. Keep the router reservation tied to the appropriate current device identity, especially if private MAC addressing is involved. A stable test with both devices online is stronger evidence than a restart that merely lets one win the temporary address conflict until the other returns.

An example to work through
For example, a manually configured TV may use an address later offered to a laptop. Playback can fail when the laptop joins. Returning the TV to DHCP or making a proper nonconflicting reservation addresses the local cause more directly than changing DNS or buying a faster broadband service.
Questions about this topic
Can restarting appear to fix a conflict?
Yes, temporarily. The duplicate assignment may recur when both devices reconnect.
Is a reservation the same as guessing a static address?
No. A supported reservation coordinates assignment through the router.
