Αν το ρούτερ δεν βρει σήμα μέχρι το βράδυ, θα πάω να δουλέψω στο καφέ απέναντι.

Αν means if and introduces a condition.

So the first part, Αν το ρούτερ δεν βρει σήμα μέχρι το βράδυ, is the if-clause:

• If the router doesn’t get/find a signal by the evening

The second part, θα πάω να δουλέψω στο καφέ απέναντι, is the result:

• I’ll go work at the café across the street/opposite

This is a very common Greek pattern:

• Αν + clause, θα + result

This is one of the most important grammar points in the sentence.

After Αν for a future condition, Greek normally uses the perfective non-past form of the verb. In traditional learner terms, this is often called the aorist subjunctive form.

So:

• βρίσκω = I find / I am finding
• βρει = it find(s) in a single complete event, used here after Αν

That is why Greek says:

• Αν ... βρει ... = If ... finds / if ... manages to get ...

and not:

• Αν ... θα βρει ... ❌

Greek does not normally use θα inside this kind of if-clause.

Using βρίσκει instead would sound more like a habitual or ongoing idea, not the single future event the sentence wants.

Because after Αν in a normal conditional clause, Greek uses δεν for negation.

So:

• Αν δεν βρει σήμα... = If it doesn’t get signal...

Even though βρει is the special form used after Αν, the negation here is still δεν, not μη(ν).

Compare:

• Αν δεν έρθει... = If he/she doesn’t come...
• Αν δεν μπορέσω... = If I can’t...

Μη(ν) is used in other environments, such as commands or after certain uses of να, but not here.

Literally, βρει means find and σήμα means signal.

So word-for-word, το ρούτερ δεν βρει σήμα is something like:

• the router doesn’t find signal

But in natural English, this usually means:

• the router doesn’t get a signal
• the router can’t pick up a signal
• the router doesn’t connect

Greek often uses βρίσκω σήμα in a way that sounds a bit more literal than the most natural English phrasing.

Also, σήμα here can refer broadly to:

• network signal
• internet signal
• reception/connectivity

The exact kind of signal depends on context.

Because Greek uses definite articles much more often than English.

So:

• το ρούτερ = the router

Even with loanwords like ρούτερ from English router, Greek usually treats them like normal nouns and gives them an article.

A native English speaker may feel that router is just a bare object name, but in Greek the article is very normal and often necessary.

Μέχρι means until or by, depending on context.

Here:

• μέχρι το βράδυ = by the evening / until evening

In this sentence, the most natural sense is:

• if the router hasn’t found/got signal by the evening

So the idea is a deadline or time limit.

Also note:

• το βράδυ is in the accusative, which is normal after μέχρι

This is a very common Greek structure.

• θα πάω = I will go
• να δουλέψω = to work / and work

Together:

• θα πάω να δουλέψω = I’ll go work
• more literally: I’ll go in order to work

Greek often uses:

• πάω να + verb

to show movement with purpose.

Examples:

• Πάω να φάω = I’m going to eat
• Πήγα να δω έναν φίλο = I went to see a friend
• Θα πάω να δουλέψω = I’ll go work

So the first verb shows the movement, and the να-clause shows the purpose.

For the same reason as βρει earlier: Greek is looking at the action as a whole, not as an ongoing process.

• δουλεύω = I work / I am working
• δουλέψω = I work, as a complete event, in a να or future-type environment

In θα πάω να δουλέψω, the speaker means:

• I’ll go and work
• I’ll go to do some work

This is a single planned action. That is why the perfective form δουλέψω is natural here.

If you used να δουλεύω, it would suggest a more ongoing or repeated sense, which is not what this sentence is focusing on.

Στο is a contraction of:

• σε + το → στο

So:

• σε = at / in / to
• το = the
• στο = at the / in the / to the

Therefore:

• στο καφέ = at the café

This contraction is extremely common in Greek:

• στο σπίτι = at home / to the house
• στο γραφείο = at the office / to the office
• στο καφέ = at the café

Yes, in colloquial modern Greek, το καφέ can mean the café as a place.

A few useful notes:

• καφέ can also mean coffee in other contexts, so context matters.
• For the place, many speakers also use η καφετέρια.
• το καφέ is common in everyday speech, especially in urban contexts.

So in this sentence:

• στο καφέ απέναντι clearly means at the café opposite/across the street not in the coffee

Απέναντι means opposite, across, or across the street, depending on context.

In:

• στο καφέ απέναντι

it means:

• at the café opposite
• at the café across the street
• at the café over there on the other side

Greek often places απέναντι after the noun in expressions like this.

So:

• το καφέ απέναντι = the café opposite / the café across

It is a very natural everyday way to refer to a nearby place whose location is obvious from context.

Because the sentence begins with a conditional clause.

The structure is:

• Αν ..., θα ...

So the comma separates:

1. the condition
2. the main result

This is similar to English:

• If the router doesn’t get a signal by evening, I’ll go work at the café across the street.

If the order were reversed, the comma might be handled differently, just as in English.

It describes a real, open future possibility.

The speaker is not talking about something impossible or imaginary. They mean:

• there is a genuine chance the router will not get signal
• if that happens, they will go work somewhere else

That is why the pattern is:

• Αν + perfective non-past
• θα + future result

This is the normal Greek way to say:

• If X happens, I’ll do Y

It is not a past unreal condition and not a contrary-to-fact statement.
