Ok, so I'm one of those grouchy ppl that can only field the same "Who's a good ISP?" question 25 times before get irritated.

So here's my bash at providing a starter FAQ for new ADSL users. I have borrowed some answers from other posts - so sue me. :)
Feel free to add Qs and As to this, but lets try keep this strictly a Q & A type thread.


*** GETTING ADSL ***

Q1: So I want to get ADSL. What do I do?

A: Before you do anything, check that your exchange is ADSL enabled by visiting the Telkom website. If your exchange isn't enabled, you can quit now.
It's usually a good idea to call 10219 to check with a consultant too, since the web list can go out of date, or be plain wrong.


Q2: What's the best/easiest way to order an ADSL line?


A: There isn't really a "best way", but some ways are better than others though:
- Telkom shops. This gives you a face and name to bug repetitively until the line gets installed. Some forumites have reported good service and decent install times when using a Telkom shop.
- 10219 or 0800 456 786 is good for installation queries. This is the "watch a movie while on hold" approach, but it does get results. I personally did this and it worked out ok.
NB: Get names and references for every step of the process, and document your calls to save hassles later.
- Use the Telkom website to sign up online. This approach will usually net you a follow-up call from Telkom, but up to 3 weeks later...not really advised.
- ISPs. Some ISPs offer to put the line order in for you.


Q3: How can I speed up my installation?

A: Generally speaking, Telkom internally is supposed to get an ADSL line installed within 3 weeks from order date.
Phoning a lot to request progress helps a bit.
Tell the consultant that you have some kind of urgent need for ADSL...
Some ppl have suggested that by putting a deposit down, it gets you some kind of priority.
If your line takes longer than 3 weeks and they are stuffing you around more than normal, make use of the Telkom customer complaints escalation.
Call 0800 600 126 and lodge a complaint. This usually starts a bit of a witch-hunt within Telkom to find who is holding your install up...ultimately it can produce results - but only do this in cases where you have proof that they have messed you around.

In some cases, you just can't. This is usually when you get told the dreaded "no ports on exchange" excuse.
In those cases, you have to wait until Telkom deign to make ADSL available for your line/exchange.


Q4: Should I sign up for one of those bundled Telkom offers that give me a free modem/installation/pc?

A: Hell no. All Telkom's special ADSL offers are contractual. They may be giving away some free stuff, but in exchange you bind your soul to Satan's little brother for 24-36 months ;)
Seriously though, currently the ADSL market is shifting rapidly in price and service. Ensure you are free of contractual obligations in order to get the best value for money as ADSL offerings WILL improve.


Q5: What hardware do I need?

A: The minimum hardware you need to get is an ADSL modem and a micro-filter for every normal telephone connection on your line. I'm assuming you have a PC :P
The modem is what you'll use to actually connect into the ADSL network.
The micro-filters are critical to ensure that your telephone service does not interfere with your ADSL service.
Off the top of my head, I can recommend buying ADSL gear from jump.co.za and digitalplanet.co.za.


Q6: What is, and where can I get, a good modem/router?

A: Search the ADSL Technical forums to decide what kind of ADSL modem you want/need.
Openly recommended makes include Billion, Dlink, Netgear.
Pricing starts at around R430 for a no-frills ADSL modem.
I recommend PPPoe capable router modems since they offer better networking and firewall options for around R100 more.
Generally speaking you want to stay away from Telkom's modems and router/modems, since they have developed a bad name quality wise. Besides, rather support a company other than Telkom whereever possible.


Q7: Who is a good ISP?

A: There a many good ISPs out there. Don't buy Telkom's story that TelkomInternet is better than rest because, by most accounts found on the forums, TelkomInternet's service and support suck.
Recommended ISPs include axxess.co.za, webafrica.co.za, imaginet.co.za, saol.com, isoft.co.za
There are other ISPs that are also good, but the above are the more well-known ones that have representives that openly engage with users on MyADSL.
If you want to get a better idea of who is better or has better pricing, visit their sites and search this forum!


Q8: What is the cap?

A: The cap is a variable usage limit enforced by Telkom on all ADSL accounts.
Once you reach your cap, you generally lose all international access whilst local websites are still accessable. Read up on the ISP products pages for more details.


Q9: Which line package should I get?

A: You need to evaluate what you want to use the line for.
Telkom charges you if you request to downgrade line speed (eg. from 512 down to 384). There is no charge for upgrading line speed though. My logic is start at 192, and upgrade free if you need/want the extra speed.

If you are mainly a web browser and email person, 512 will be overkill - 192 should suit you fine.
For heavy downloaders or people that want to watch streaming videos, then go for 384 or 512.
Generally speaking all 3 HomeDSL products perform equally well in terms of online gaming - both locally and internationally.


Q10: What speeds can I expect on 192/384/512?

A: Pretty much consistently 80% of the package speed. Some people report getting 384 speeds on 192,and 512 speed on 384, but this is fairly rare.
International can be slow for P2P apps because standard port-shaping is applied, meaning your p2p gets less priority allocated to it.
International gaming also suffers poorer latency and throughput because of the shaping.


Q11: What is the difference between shaped and unshaped ISP accounts?

A: Unshaped is free of the standard port-shaping that hampers most applications besides web browsing and email.
Its a lot more expensive though, and generally is only for people that simply have to have the fastest and best speeds and latencies to international sites.
Unless you are a really serious online international trader or gamer, the normal shaped account should be fine for most uses.
Of course, shaping is a Telkom imposition on the service, internationally speaking port-shaping is not nearly as harsh as Telkom's.


Q12: What are the installation costs involved for ADSL?

A: Assuming you have an existing line, the charge is R404 once off.


Q13: What are the monthly costs for ADSL?

A: Monthly costs are broken into two seperate fees: ADSL line rental and ISP acount.
- The ADSL line rental is paid to Telkom and is dependant on which speed package you choose. Pricing is on Telkom's website.
- The ISP account is paid to your ISP and is dependant on which size cap package you choose.

Bear in mind, that Telkom continues to charge telephone line rental over and above the 2 costs above. Telephone line rental is around R95 for residential.

Great stuff Lews! Long time coming. I think it should be a "DIY" type thread, where the community can submit their own questions with answers. Thanks!
 
Thank you

Well done on this thread. :)

I wish this had been around a week ago, as it would have saved me many hours!!

Thank you for your effort on behalf of many newbies to come
 
OK this has enlightened me.

I was looking on digitalplanet and i saw the Netgear DG834UK router for R847. Is this a good router? It says it has firewall and 4 port switch - product link
Should i rather get this than the telkom supplied modem? If i do get the router myself, do i need to get the micro-filter as well?

Vega. Like I mentioned in my "what modem" answer, the question of what modem to get is very dependant on what purposes you have for it. Netgear are a good brand, I don't think you can go wrong with ithe modem/router above.
I personally have a Billion 5102S, and it works great for my little home network.
It was a no brainer to set up, and has decent enough routing features.
The 5102S has only one lan port (I already have a switch), but you can also get the Billion 5102 which includes a 4 port switch.

Regarding the micro-filter - thats a definite yes. Telkom don't supply the micro-filters, so rather get your own. Remember you need one for every phone you have plugged into your ADSL line.
 
More FAQs

Some more questions I've seen too regularly to answer again :)

Q14: Ok, I've ordered my ADSL line from Telkom. When should I buy my modem/ADSL gear? When should I get my ISP account?

A: Generally speaking, do not trust anything Telkom says regarding install dates - and as such, buy your stuff at the last minute.
I was given a date, and eventually my line got installed 2 weeks later than that.
Several people have posted about being given an install date, only to be told a few days later that their exchange has no ADSL slots available.
You don't want to end up in a situation where you've shelled out R700 for hardware you can't use.
I advise placing the order for your gear when you get a call from the Telkom techie wanting to confirm a time he can visit to do the install.
At this stage you're can be fairly sure that you will be getting ADSL soon.

For the ISP side you can get an ISP account activated in about 2 minutes, 24/7, with most of the ISPs I mentioned above.
So that should be the thing you do as the Telkom techie drives away ;)


Q15: What size cap ISP account do I really need?

A: This is a tough one, and once again dependant on your usage aims for your ADSL connection.
If you are going to be using your connection mainly for web browsing, email and the odd file download, then a 3GB account will be fine.
However, the moment you regularly play online games - particularly shooter games like Counterstrike, watch/listen to streaming video and audio, download large files, and generally start using your ADSL connection for what it was designed for - then you will probably exceed your cap.

There are now "higher cap" accounts available ranging from 4GB - 30GB
See the ISPs above, and pick your cap size :)


Q16: What technical settings should I be using for my modem/router?

A: Modem/Router Settings
Protocol Type: PPPoE
VPI: 8
VCI: 35
Encapsulation: LLC

Besides the above, if you have taken my advice and selected an ISP recommended by people on these forums, then you can call a decent support person at your ISP. :)

A comprehensive FAQ, well done!
NO more repeated questions about ISP, etc! horay!
 
What is ADSL?

You left out the most obvious question. :p

Q17: What is ADSL?

ADSL (Asymmetric Digital Subscriber Line) is a technology that allows fast Internet access from your home or office. ADSL uses the existing physical capabilities of your land phone line.

And for good measure.

Q18: What are the advantages of ADSL?

- There are no dial-up per minute charges.
- No need for a second phone line (data and voice over same line).
- 24/7 connection to the Internet.
 
I have another question will the fact that an ISP being in a different Province to me, increase my Ping?

No, all the ISP really do is authenticate and cap you when neccessary. SAIX bandwidth is SAIX bandwidth.
 
One (or so) question I have, as I may just make the leap by applying for ADSL tomorrow:

What do I need to be able to share the connection between two computers? Do I need additional specific hardware? Would I be able to do this with an ADSL account from the likes of Axxess', or WebAfrica's 30 gig offerings?
 
You can share the connection irrespective of the whether the account allows for concurrent connections or not, if you have the necessary hardware for this at the site concerned. Best way to do this (though not the only way), is to have a 'router-modem' device plugged into a switch/hub. Hence, wall-plug <-- ADSL router-modem --> switch/hub <-- 2 or more PCs.
There's lots of threads on this forum that address this question, including advice regarding the best router-modem to get - do a search.
 
This is a brilliant thread!

Somebody should compile a FAQ document and link to it from the MyADSL frontpage :)


Q19: What does the Telkom techie actually do when he comes to 'install' ADSL. Is there some sort of equipment that ges installed between the line and the ADSL modem?

Q20: Do I need a microfilter for the connection between the wall-box and my ADSL modem or simply on those lines that I will also have a phone line?

First part: There's nothing really to be done, if you have a 'clean' line to the nearest DSLAM. If not, (s)he puts a tone generator on your end and tracks it all the way through the pole boxes/RB7 boxes to determine/establish a continuous 'clean' line to the DSLAM at the exchange. Second part: No.

No. The filter is only for the phone/fax/whatever device.
