Jeg klarer ikke å logge inn i nettleseren, så jeg ringer supporten.

å is the Norwegian infinitive marker (like English to). After many verbs—including klare—Norwegian commonly uses å + infinitive:

• å logge = to log in (with inn completing the meaning)

logge inn works like a Norwegian “phrasal verb”: logge + particle inn.

• logge inn = log in
  The particle often comes after the verb, and it can sometimes move in other sentence types, but here the basic infinitive form å logge inn is standard.

Both are possible, but they’re used a bit differently:

• å logge inn is very common and often doesn’t need an object (it’s understood that it’s you logging in).
• å logge meg inn is also correct and can feel slightly more explicit.
  So your sentence is perfectly natural without meg.

Norwegian uses different prepositions than English. i often corresponds to English in for “inside/within something,” and it’s common to say:

• i nettleseren = in the browser (i.e., within that program/environment)

That said, depending on what you mean, Norwegians might also say på nettsiden (on the website) or på kontoen min (on my account)—but i nettleseren is grammatically fine.

nettleser = (web) browser
nettleseren = the browser (definite form)

Norwegian often marks the by adding an ending to the noun:

• en nettleser = a browser
• nettleseren = the browser

In a normal main clause, Norwegian typically puts ikke after the finite verb (the verb that is conjugated for tense):

• Jeg klarer ikke ...
  This is one of the most common negation patterns in Norwegian main clauses.

The comma shows you have two main clauses joined together, and så here means so (result/consequence):

• I can’t log in..., so I call support.

It’s essentially: [problem], so [response/action].

With så meaning so as a conjunction connecting two clauses, you typically keep normal word order (subject before verb) in the second clause:

• ..., så jeg ringer supporten.

If Så means then as a sentence adverb placed first in the clause, you usually get inversion:

• Så ringer jeg supporten. = Then I call support.

So both patterns exist, but they signal slightly different functions of så.

Norwegian present tense often covers both:

• I call
• I’m calling
• I will call (in some contexts)

Here jeg ringer supporten naturally means I’m calling support (now / as a result).

Yes. support is used in Norwegian (especially in tech contexts), and it commonly appears as a masculine noun:

• support = support (general concept)
• supporten = the support / support (the support department/team)

Using the definite form often implies a specific support function you both know about (e.g., the company’s helpdesk).

Both are used, but they’re not identical:

• ringe noen = call someone (direct object) → Jeg ringer supporten.
• ringe til (et sted/en tjeneste) = call to (a place/service/number) → Jeg ringer til supporten.

In everyday Norwegian, Jeg ringer supporten is very common and completely correct.
