Musiałam przestawić router bliżej drzwi, żeby w sypialni też był internet.

Musiałam means I had to said by a female speaker.

Polish past-tense forms agree with the speaker’s gender in the 1st person singular:

• musiałam = I had to (female speaker)
• musiałem = I had to (male speaker)

By contrast:

• musiał = he had to

So musiałam tells you both:

1. the subject is I
2. the speaker is female

Polish often leaves out the pronoun ja (I) because the verb ending already shows the person.

It means I had to or I needed to in the sense of necessity.

The structure is:

• musieć = to have to / must
• musiałam + infinitive = I had to do something

So:

• Musiałam przestawić router = I had to move/reposition the router

It refers to a completed necessity in the past: at some point, the speaker found it necessary and did it.

Przestawić means to move something to a different place, to reposition, or to shift.

It is a very common verb when you change the location of an object:

• przestawić krzesło = move the chair
• przestawić lampę = move the lamp
• przestawić router = move/reposition the router

The prefix prze- often suggests changing from one arrangement/position to another.

In this sentence, przestawić router is more natural than a general verb like przenieść if the idea is not “carry away” but simply “put it somewhere else.”

After musiałam, Polish normally uses the infinitive, not another finite past form.

So:

• musiałam przestawić = I had to move

not

• musiałam przestawiałam ❌

Also, przestawić is a perfective infinitive, which fits well here because the sentence refers to a completed action: the router was moved to a new place.

A rough contrast:

• przestawiać = to be moving / to move repeatedly / to move in general (imperfective)
• przestawić = to move once to a new position, successfully (perfective)

Here the speaker means one completed action, so przestawić is the natural choice.

Yes, many Polish verbs require a specific case. Here, router is the direct object of przestawić, so it appears in the accusative.

But router is a masculine inanimate noun, and for many such nouns, the accusative singular looks exactly like the nominative singular:

• nominative: router
• accusative: router

So the form does not change visibly, even though the grammatical case has changed.

Bliżej means closer / more near, and it is followed by the genitive in Polish.

So:

• bliżej czego? = closer to what?
• bliżej drzwi = closer to the door

The noun drzwi is in the genitive here.

A useful pattern:

• blisko domu = near the house
• bliżej okna = closer to the window
• najbliżej wejścia = closest to the entrance

So bliżej commonly triggers the genitive.

Because drzwi is one of those Polish nouns that is plural in form, even when it refers to a single object.

So although English says door in the singular, Polish uses drzwi, which behaves grammatically like a plural noun.

That is why you get forms such as:

• te drzwi = this door / these doors
• do drzwi = to the door
• bliżej drzwi = closer to the door

This is similar to how some English nouns are plural in form for a single thing, though the exact examples differ.

Żeby introduces a purpose clause here: so that / in order that.

So:

• Musiałam przestawić router bliżej drzwi, żeby w sypialni też był internet.
• I had to move the router closer to the door so that there would also be internet in the bedroom.

Why not the others?

• żeby = so that / in order to
• aby = also means so that, but it sounds a bit more formal/bookish
• bo = because

So bo would change the meaning completely:

• bo gives a reason
• żeby gives a goal/purpose

Here the second clause explains why she moved the router in terms of intended result, so żeby is exactly right.

This is a very common thing that confuses learners.

After żeby, Polish often uses forms that look like the past tense, but in this structure they do not simply mean past time. They are part of a subordinate clause of purpose, wish, result, etc.

So:

• żeby był internet = so that there would be internet / so that the internet would be available

Here był is not really telling you “the internet was” in a straightforward past-time sense. It is part of the żeby + past-form-like verb construction.

You can think of it as expressing a desired or intended situation:

• the router was moved
• with the goal that internet access would be available in the bedroom

Because internet is the subject of the clause, so it is in the nominative:

• był internet = there was / there would be internet

And the verb is był because internet is grammatically singular masculine.

So:

• internet = singular
• był = singular masculine past-form

Not były, because były is plural or feminine non-masculine-personal.

Also not internetem, because that would be the instrumental, which is not needed here.

Literally, yes, but more naturally in English it often means:

• there was internet
• there was internet access
• the internet worked
• there was Wi-Fi

In Polish, expressions like jest internet or nie ma internetu are very natural when talking about availability of connection.

So żeby w sypialni też był internet is best understood as:

• so that there would also be internet in the bedroom
• or more naturally: so that the bedroom would have internet too

W can take different cases depending on the meaning.

Here it means in, referring to location, so it takes the locative:

• w sypialni = in the bedroom

The base noun is:

• sypialnia = bedroom

Its locative singular is:

• w sypialni

Compare:

• w kuchni = in the kitchen
• w łazience = in the bathroom
• w pokoju = in the room

So w + location usually gives the locative.

Też means also or too.

In this sentence:

• żeby w sypialni też był internet
• so that there would also be internet in the bedroom

It highlights that the bedroom should have internet as well, probably in addition to other rooms.

Its position is flexible, but word order changes what feels emphasized.

For example:

• żeby w sypialni też był internet = so that there would also be internet in the bedroom
• żeby też w sypialni był internet = also in the bedroom
• żeby w sypialni był też internet = the internet is what is being added there too

All are possible, but the original sounds natural and neutral.

Because Polish has no articles like English a/an/the.

So Polish simply says:

• router
• drzwi
• sypialnia / w sypialni

Whether English should use a or the depends on context and translation, not on a separate Polish word.

That is why one Polish sentence can correspond to different English versions, for example:

• I had to move the router closer to the door...
• I had to move a router closer to the door...

Usually context makes it clear which one is meant.

Yes, that is a perfectly good translation.

Bliżej is the comparative form of blisko:

• blisko = near
• bliżej = nearer / closer

So:

• bliżej drzwi = closer to the door / nearer the door

English may prefer closer to, while Polish simply uses bliżej + genitive.

Polish word order is relatively flexible, but different orders change emphasis and naturalness.

The original sentence is very natural:

• Musiałam przestawić router bliżej drzwi, żeby w sypialni też był internet.

Other versions are possible, for example:

• Musiałam przestawić router, żeby w sypialni też był internet, bliżej drzwi.
  This sounds awkward, because bliżej drzwi is separated from the verb it belongs with.

• Router musiałam przestawić bliżej drzwi, żeby w sypialni też był internet.
  This emphasizes router.

• Żeby w sypialni też był internet, musiałam przestawić router bliżej drzwi.
  This emphasizes the purpose first.

So yes, word order can change, but the original order is the most straightforward and idiomatic.

Yes:

• Musiałam = I had to (female speaker)
• przestawić = move / reposition
• router = router
• bliżej drzwi = closer to the door
• żeby = so that
• w sypialni = in the bedroom
• też = also / too
• był internet = there would be internet / internet would be available

So the structure is:

[I had to] [move the router] [closer to the door] [so that] [in the bedroom too] [there would be internet].

That makes it easier to see how Polish builds the meaning step by step.
