With physical higher broadband speeds becoming available terrestrially, there will soon be a new constraint and that is the ISP. Your contract with an ISP does determine how much information you can download and upload. If you had a 1MB line then you would sign up for a 1MB package from the ISP. There would be no point in paying for a 4MB package. Now with dramatically increased speeds the ISP may become the constraining factor. This was the case recently that I cam across. Their router was showing 22MB connectivity for download and the ISP under speed test was showing download at 3.5MB on a 4BM ISP contract (which is not bad). Loads of people replied much the same as I did. I agree with what has been said before regarding the physical connection and the download achieved. Nothing to complain about there. It does remind me though that it is good practise to run speed tests occasionaly especially as ADSL upgrades are rolling out at the moment. It may also be a good idea to re-boot your router every few days so that if the line has been updated you can get the benefit of it. Anywho your ISP is going to limit you to the bandwidth that you are contracted for. Warmest regards Tim

My data has gone down awfully quickly

Connecting to the Internet whether fixed line or mobile has a number of hidden pitfalls. Leaving it permanently connected and using up your sometimes precious allowance of data in tasks you did not know about is one of them. This was the case with one post that I came across where a good well intentioned son had purchased a data bundle from one of the cell providers to allow him access to mail. He found his data consumed and far more than sending and receiving an email would do. He found that Windows was turning on updates again as it does. Others commented on this and he corrected the problem but I had an additional suggestion or 3. Windows updates and do you do them automatically, manually or not at all is a good debate. What I did with my father who is very advanced in years was to disable all updates completely. He brings his laptop round every 3 months or so and I connect it to my LAN and BroadBand connectivity and do the updates that way. I do the same with his anti virus as well. It might be sensible as well with those of advancing years to remind them that in their youth they would not have left the phone off the hook or they were charged for the call. So it might be an idea to unplug the modem after accessing mail. Anywho that is my suggestion

Extending Wireless coverage is a cable not easier?

I came across a post that intrigued me a bit. If one has weak wireless signal how can it be boosted? The post went into some options and gave a good description of the problem. The router is in the main building and the user 5m away physically from the main building and 15m from the router so yes there would be some degredation of signal. A few peopole including me would suggest cable and this is what I said: I would go the cable route. Firstly it will ensure that you have better speed to the ADSL router and that is I believe one of your main concerns. Secondly you are likely to spend less. In running the cable I would say it pays to make a bit of an effort to make it neat and tidy to stay in the landperson\'s good books. Assuming that the area between your cottage and the house is garden, I would suggest digging a trench and laying the cable at about 40cm depth which is out of reach of most garden spades. Do encase it in normal electricians PVC conduit and put at either end proper elbow joints and run the conduit up the wall. I would even drill through the walls (check for electrical and water pipes first) and make it a neat and tidy job. Where it goes into the wall it is a good idea to put an inspection box in as at times it can be difficult getting cables round bends and having these boxes lets you get an electricians fish in easily. To make life a little easier you could run the cable or strong string through the conduit before you bury it and then either pull the cable through or just push the ends of the cable through into the house. Remember to use the PVC cement to join all the connectors to make them watertight. If there is paving between then you will need to lift it carefully and put it back. A word of warning though, it never looks the same so make sure the landperson is happy that you do it. If it is cement then I suggest you go back to looking at the wireless extenders or find another route even if it is more than 15m. Good Luck

I was immediately attracted to a post the other day on how to protect code that you have written from being decompiled. Intersesting problem and one that the software license agreement is meant to protect you from. But that agreement is one that many people feel should not include them. Decompiling object or run time code has always been listed as one of the things not to do by the person signing the license agreement. So here wwe have a developer who has created some code that they want to protect. Obfuscation is a way of providing some protection by literally causing de-compilers to produce rubbish. Some responses indicated using a combinatin of tools and that is a good route to follow. My response after a bit of research was Looking around the Web there are plenty of tools to assist. One which came up quite frequently for me was smokescreen http://www.leesw.com/smokescreen/ Another was allatori http://www.allatori.com/ This one provides regular updates and lists some large companies that are using it. Could be worth a try. At the end of the day decompiling is what some people will always try to do. you just want to make it more difficult to do than someone else. So protecting yourself is always a good idea but plagerism is as rife in programming as it is in other creative forms.

My HSPA is now on (the) EDGE

We are all expecting to get the best connectivity at all times don\'t we? Certainly for me as an employee of MTN Business, I want to have the best no matter what technology I am using. In one of the forums I frequent a user was frustrated that no matter what they teiewd the best speed they could get was EDGE in one laptop but move the sim to another device and HSPA was available. One reply was I thought very good and they suggested de-installing the driver software, rebooting and then reloading. However what wass critical was that the USB modem then always be inserted in the same USB port. It sparked a memory in my mind. I few months ago working with a USB memory stick I seemed to get better performance when it was inserted in one port rther than another. I must admit that at the time I dint do too much technical research into it but just made sure I always used the same port. Their suggestion was essentially the same as what I was doing. I agreed as you can see below. Hi there Rollerball, I agree with gings that it is unlikely that the software is corrupt. Teraside has a good suggestion. I have noticed when connecting USB devices that on some ports it is slower than on others. I now try and connect the devices to the prot they were originally connected to. Hopefully it will help resolve the problem and I look forward to reading about if it does or not on this forum. Has anyone else come across this?

What software would you install on a new PC

We all have our favourites don\'t we? the little bits of software, the favourite can\'t do without application. A post I read last night asked the question what would you load on a new office PC with Windows 7? The responses included a list of several really good applications including simple things like anti virus, codecs, opensource office software. The list is of course potentially endless. Being the cost conscious MTN Business person that I am I felt the list needed to have something that looked at ongoing rather than capital savings. So my suggestion was as follows: If it is for office or even personal use I would want to have a simple messaging and even VOIP tool. I use SKYPE at home and in the office. Simple to use and gets communication round faster than email does. If you are going to be making calls to other offices then it can save you a lot of money on telecommunication costs. For overseas communications I use it a lot to suppliers in Europe. Regards Tim the Techxpert

USB connectors are great devices but they can at times be how can I put it a little delicate so you do have to treat them with care. A recent post revealed that someone had damaged the USB connector on his router that he used for data transferring. Another reader suggest going for a warranty replaement which I agreed with but then I added on a bit more advice which applies to any USB device: I agree with Sajunky go the warranty route first especially as it is less than a month old. Repairing a USB port can be difficult at best. Just a tip: I know that we all do tend to just thrust our USB connectors into the devices and it can be easy to damage the female and the male portion of the connection. If you are going to be removing it frequently, why not get a USB extender cable and leve that plugged into the router and then connect the USB device to the cable. In the event of damage you are only replacing a cable and not a router. I would not recommend an expander port though as you do loose signal speed without booster power. Anywho I wish you well in getting it fixed

Someone is sending information that they shouldnt!

As employees we are expected to follow the rules and morals of the society we live in. As employers we have a duty to ensure that the rules are followed and that confidential information that should stay inside the company does stay inside the company. Take a post I came across today. They were looking for a way to disable delting in outlook so all messages that were sent could not be removed or if that was not possible then saved somewhere else or forwarded to another person. The reason was they suspect that an employee is leaking confidential information. There were some replies many of which were more interested in what the person was suspected of doing but I did add my view It would be really useful if Outlook rules ran on any folder and not just when a mail is received. It is possible to do it but you would be into creating VB scripts to do it. If your email host can supply copies of mails that would be useful as it would be an independent witness in the event of inappropriate action by your employee. I would suggest that if you do not have an email policy signed by all employees that you implement one immediately. It should cover inappropriate use of the internet (sites for over 18s etc) and you could include less sensitive sites such as facebook, twitter, gmail although you could block those sites anyway. It should also state that all emails sent are the property of the company and that your management can read all emails. If you have locked all this down then sad to say you are still vulnerable in that they may be sending information via cellpohone in either text messages or internet connectivity. Good luck. It is not pleasant if you suspect an employee is acting inappropriately and if that is the case the actions you take, although necessary, can cause resentment in the office but they need to be taken.
