Hi! When a Roku TV cannot sign in to your account, it’s usually not “just the password.” There are a few common buckets, and the right first step depends on what you’re actually seeing on the screen.

Can you tell me which screen you’re stuck on?
• A Roku “link/activate” screen asking you to go to a website and enter a link code (like my.roku.com/link).
• An email + password sign-in page on the TV that says your login is incorrect or can’t be processed.
• An error that looks network-related (can’t connect, service unavailable, request failed, or it keeps looping back).

Also: did this start after a power outage, router change, or a Roku software update — or did it happen during initial setup?

Perfect — the “sometimes login, sometimes connection” mix is the key clue. Roku can look connected to Wi-Fi but still fail the specific connection it needs for account verification (DNS filtering, captive portals, or intermittent routing). And if you’re trying to add a channel, the account check tends to be stricter than normal streaming.

I’ll ask in a slightly unusual order (risk-first) so you don’t accidentally trigger a bigger mess:

1) Are you on home Wi-Fi or something like hotel/guest Wi-Fi? (Guest networks often block the “sign-in” handshake.)
2) Do other apps on the Roku still stream right now? Even YouTube or a free channel? Or is everything flaky?
3) Do you use any ad-blocking DNS, Pi-hole, VPN on the router, or “family filter” settings?

And a quick safety note: we can diagnose without factory reset. We’ll treat this like either a Roku account authentication issue or a network path issue and prove which one it is.

That’s a very believable combo: streaming works (so you feel “online”), but account actions fail (because those calls can be blocked or more sensitive). Two things stand out: ad-blocking DNS and possible wrong email/account.

Here’s a safe way to separate them without changing the TV setup yet:

• First: confirm the account credentials away from the TV. The Roku TV keyboard and password entry are error-prone, and if you have multiple accounts, it’s easy to use the wrong email. If you can sign in successfully on a phone/laptop to your Roku account, that tells us the credentials are valid and the TV/network is the problem.

• Second: confirm whether this is a “linking” flow or true TV sign-in. Some Roku setups don’t want your password entered on the TV at all — they prefer a link code on a website. If the TV flips between these screens, it can look like “can’t sign in.”

On your TV, do you ever see a screen with a link code and instructions to visit a Roku link page (like my.roku.com/link), or is it strictly email/password every time?

You’re thinking about this the right way — repeated attempts can create more confusion, especially if you’re mixing accounts. Also, link codes can expire, so a “timeout” doesn’t automatically mean your account is bad.

When you get both (code screen + email/password prompts), it often means the Roku is bouncing between activation/linking and account verification because it can’t complete one step reliably.

Two quick diagnostic questions (no changes required):
1) Is the Roku TV date/time/time zone obviously wrong? (Even just “it thinks it’s yesterday” or the wrong time.) Some secure sign-in flows fail if the device time is off.
2) When the link code fails, does your phone use the same Wi-Fi, or is it on mobile data? If the link works on mobile data but not on Wi-Fi, that points back to DNS/router filtering.

Also: do you see any specific error numbers (like a network error code), or is it more generic “can’t connect” / “unable to sign in”?

The outage + Wi-Fi-only link attempt makes the network path the “top suspect,” with the multiple-account possibility as the “second suspect.” Netflix working doesn’t rule it out — streaming can succeed while account endpoints fail or get blocked.

Here’s the safe logic to follow (still not doing anything destructive):

Step A — prove the account: make sure the email/password you’re using is correct by signing in on your phone/laptop. If you’re not 100% sure which email is tied to the Roku account, that’s where confusion usually starts (especially in households with more than one account).

Step B — prove the network path: try the link code page once on mobile data (not Wi-Fi) just to see if the activation flow behaves differently. If it suddenly works, the issue is likely your home DNS/router filtering, not the Roku account itself.

Step C — prove the Roku connection quality: check whether the Roku reports a solid connection (not just “connected”). Mesh systems can sometimes steer devices in ways that look like random sign-in failures.

One more symptom question: does the Roku TV stay logged in once it works, or does it keep prompting you again when you try account actions like adding channels?

Totally understandable — and yes, a factory reset is exactly the kind of thing you don’t want as a first move. The good news is, you can get a lot of clarity without touching that.

Simple explanation: Roku sign-in failures usually come from one of two places:
• The account side: wrong email, password mismatch, password reset needed, or you’re using a different Roku account than the one originally linked.
• The network side: the Roku can’t reach the account/activation services reliably (DNS filtering, router security features, captive portal behavior, or unstable routing after an outage).

Since you suspect multiple emails, I’d treat this as “account identity” first — because if you use the wrong email, every other test becomes confusing.

Safe question: do you have access to the email inboxes (yours and your dad’s) to check which one gets Roku emails (receipts, password reset emails, or “welcome” messages)? That’s often the fastest way to confirm the correct Roku account without guessing.

Great — and we’ll keep it “safe help” only: diagnostics, not wipe steps.

Once you confirm the correct email/account, the safest order on the TV is:

1) Verify the Roku has a stable internet path (not just “Wi-Fi connected”). If the TV can’t reliably reach Roku services, sign-in and channel adds fail even when Netflix works.

2) Restart the Roku system cleanly (a normal system restart is not a factory reset). After outages, the Roku can get “stuck” in a half-working state where streaming works but account checks don’t complete consistently.

3) Use the link-code method if offered (enter the code on the official link page). It reduces typing errors and avoids the TV keyboard problem. If the code fails on Wi-Fi but works on mobile data, that’s strong evidence the home DNS/router filtering is interfering.

4) Only after those proofs would you consider deeper steps — but we’re not jumping there here.

If you tell me what error text you get on the last attempt (even roughly), I can help you map it to “account” vs “network path” without guessing.

Sure — here’s the calm, safe checklist.

Simple explanation: When a Roku TV can’t sign in, it’s usually either (1) the wrong Roku account/email/password is being used (very common in families), or (2) the Roku can’t reliably reach the activation/account services even though Wi-Fi says “connected” (often due to DNS filtering, router security features, or instability after an internet outage).

Safest checks first (no factory reset):
1) Confirm the correct Roku account email by signing in on a phone/laptop and checking which inbox receives Roku account emails.
2) If you see a link code on the TV, use the official link-code flow instead of typing passwords on the TV keyboard.
3) Test the link page once on mobile data vs Wi-Fi to detect router/DNS filtering (diagnosis only).
4) On the Roku, confirm the internet path is stable and do a normal system restart if it got flaky after an outage.

If you do those in order, you’ll know whether you’re dealing with an account identity issue or a network path issue — without wiping channels or settings.
