Internet access blocked / activation does not work

I have been living in a furnished room in a former hotel for years. The landlord, who does not live here himself, has set up a communal Wi-Fi internet connection for all residents…

THAT is of course bad…If only one device of all residents makes a mess, then the entire network is dead in the event of a blockage…

Of course, it also depends on WHAT EXACTLY the landlord has for a WiFi solution in the background. A home or business subscription? Do all users use the same WiFi credentials or separate ones?

This is a miserable solution. And with 10 tenants he makes quite a bit of money…

I don’t even know if this is even allowed…

@Piongietzei94

Registration normally works via the link below and that would be the responsibility of the owner of the subscription!

A Swisscom login and password are required and this has nothing to do with the network, the subscription holder has this information.

In any case, this distribution is not the best because everyone can do what they want and somehow there is no control.

If a private Swisscom Abo is made publicly accessible, you must expect that the Internet connection will be blocked at any time. This mostly happens with email, spam and viruses. Swisscom is interested in ensuring that its Bluewin servers do not end up on block lists.

But if a repair is even necessary, this can only be done using the serial number or the Swisscom login of the connection. You tenants are unlikely to have that.

If we assume that the WLAN is not operated professionally, a blockage must be expected at any time.

If the WLAN is operated professionally, various technical measures are necessary, which are unlikely to be implemented as access with a Swisscom private customer subscription. Well, I wouldn’t do that, but there are plenty of weirdos on the market who might still come up with such an idea.

I would recommend that the landlord sets up something proper if he hasn’t already done so (radius, logging, proxy, etc.). Otherwise the Anschluss will be blocked again sooner or later.

Or as @Hitch hilft says, get a Anschluss yourself and disconnect from the landlord’s WiFi.

The question again: are the same websites also blocked for the landlord on his own device when he comes here? Otherwise he won’t see the access blocked message and won’t be able to activate it.

Yes, don’t worry. The Internet is now closed to everyone and anyone who wants to surf comes to the splash page.

@Piongietzei94

I understand the situation on site. You simply cannot work around the problem with this existing solution.

Another variant: You could of course also get a mobile subscription (for 50.–) from a provider. And get an LTE router. e.g. Huawei and insert the SIM card there. Afterwards you have your own WiFi etc. also for the 50.–

Of course it would be an advantage if you had 4G in the apartment.

I still have to ask again now. Only a few sites are blocked?

Unfortunately, too much has already been written that I just read across 😄

Can you post a screenshot of the lock page?

Because you have to differentiate between complete blocking, blocking by Swisscom’s DNS Guard or even another blocking of a 3rd party product.

Is there any information from Swisscom about these internet blocks (especially the causes and how they can be prevented) that I could send to the landlord (with the request that it be forwarded to the other tenants)? I can only find posts about this in the community forum, but nothing “official”.

I don’t know if there is an official “brochure” or something like that.

But the situation is actually explained quite quickly: As soon as one of the (numerous and changing) users catches a malware on their computer, for example, which then starts sending SPAM or something similar, the Anschluss is blocked for ALL users.

This can hardly be avoided with the way this Anschluss is now operated (which is not really “intended”), unless you are lucky enough that all users always stay clean…

When it occurs for the first time, the whole thing can be unlocked relatively easily. However, only for the connection owner, i.e. not for you tenants, who probably don’t know the corresponding Kundencenter access data (not the same WiFi access data!) anyway.

If this happens again, this will also become more complicated for the landlord, because Swisscom only initially accepts an assurance from the customer that everything is now OK. If, despite such assurances, abuses continue to occur, people will soon want to know more precisely what measures have been taken.

In short: For this type of use, a more professional WLAN system would actually be appropriate, in which the individual user can be identified. Of course, it costs a little more than simply installing a Swisscom home customer router and then passing on the subscription x times over to your subtenants.

@Tux0ne

This is probably the normal connection blocking that we are assuming here.

I have noticed on several occasions in the past that the blocking process is sometimes not “clean” (i.e. some pages work, some don’t).

I’ve already asked a Swisscommer about why this is the case. Of course he didn’t know how to stammer much. Maybe their locking mechanism just doesn’t work properly 😉

Incidentally, we can also safely assume that the WLAN here is operated “non-professionally” (according to BÜPF terminology). This will simply be some homeowner who has earned a golden nose by taking out some Vivo Casa subscription and now “subletting” it. (I think even if a “professional” had told him that, it still wouldn’t count as a professional business. The law seems pretty “tame” to me. In the end, this only affects “external” operators à la Monzoon, So probably not even the electrician/networker who sets up a public WiFi in the restaurant, unless he then operates it centrally.)

@Piongietzei94

In order to completely decouple yourself from the owner, here is another example of an unlimited LTE high-speed Anschluss (available from various providers, but probably not from Swisscom):

[https://www.sunrise.ch/de/privatkunden/mobil-abos/mobile-internet/hotspots/hotspots-fuer-zuhause.html](https://www.sunrise.ch/de/privatkunden/mobil- abos/mobile-internet/hotspots/hotspots-fuer-zuhause.html)

With such offers, it is of course crucial to check beforehand whether the respective mobile network has enough power at the desired location. By the way, good 4G is more than enough, waiting for a not yet fully developed 5G is absolutely unnecessary.

There are different locks, as @Tux0ne already mentioned.

1. Internet Guard

Internet Guard blocks sites that are classified as “dangerous”, the reasons for this are usually phishing, drive-by infections or similar. All other pages can be accessed.

2. Blocked due to spam/botnet

If the Anschluss is blocked because a client sends spam or botnet traffic is detected, then you will be put in a sandbox. A sandbox only allows access to certain pages. This also includes antivirus manufacturers.

However, since the sandbox must maintain a list of domains and/or IP addresses of the websites, it may well happen that certain sites such as Kaspersky can no longer be accessed if the domain or IP address of Kaspersky’s web server changes. Swisscom should take note of this and update the sandbox.

It’s relatively easy to get out of the sandbox twice, but things get more complicated the third time.

3. Suspension due to unpaid invoices

As far as I know, there is also a block/sandbox if invoices have not been paid, everything is then blocked, i.e. no internet access and you are redirected to a page which informs you that there are still outstanding invoices. (I’ve never seen these personally…)

4. “Block” at new Anschluss

With a new Anschluss you are also in a sandbox. However, this redirects all requests to a registration page. However, this should only be activated for new or not yet initialized connections.

Basically, you as a tenant are powerless.

The landlord can unlock the Anschluss, but if one of the roommates accesses the WiFi again with a “contaminated” device, then the Anschluss will be blocked again and the whole thing starts again.

If I were you, I would use your cell phone as a hotspot. Depending on where you live, this should be possible without any problems with your current subscription. The subscription should simply not be throttled (speed) and should not have a limited data volume. I do this all the time with my cell phone, but it may work better in the city than in the country…

@cslu, there have been no problems with the Internet for 10 years. It has been constantly malfunctioning since August 2018. It also seems to me that the problems that have been going on for a year are at least partly caused by Swisscom. I say again: why is Kaspersky blocked (as one of very few sites)? There is no logical explanation for this. If Kaspersky wasn’t blocked, I would probably just leave the block as it is and work around it to avoid another level of escalation with further blocking. Of course, this is not possible if Swisscom blocks the anti-virus software. The problem here is partly caused by Swisscom, as there is currently no full protection (and until the landlord takes action).

As I said: It’s not clear to me why it’s only blocked “selectively” or, in my experience, it’s not always like that.

I once explicitly asked a Swisscom employee this. At first he didn’t really want to think of anything to say about it, but in the end he said that the first escalation stage wasn’t about blocking everything completely, but rather just making the customer aware that there was a need for action.

Whether it makes sense to block Kaspersy here remains to be seen… although I wouldn’t put too much trust in the snake oil mafia 😉

Regarding your derivation in the last sentence: I understand what you mean, but

- The infection obviously took place before the lockdown, i.e. cause and effect should not be mixed up chronologically.

- There can be no talk of “full protection” anyway. Beating oil is 95% marketing and 5% effectiveness.

And last but not least: The fact that the Internet ran smoothly for 10 years under such “conditions” may also have been due to a bit of luck. Maybe Swisscom is blocking more aggressively these days than before, I can’t say that with certainty.

In any case, Swisscom has always vehemently denied the fact that there are cases in which blocks are blocked “for no reason”. Especially in a case like the one at hand, we have to assume that there is a cause in one of your “roommates”.

But… apart from asking the landlord (or getting “independent” internet) there’s not much you can do. 4G broadband routers work if you have reasonably good reception at the location and are not in a completely overloaded radio cell.
