ADSL wide band uses some common problems in process

ADSL( the asymmetrical digital loop of Asymmetrical Digital Subscriber Loop of subscribers feeder) are one in xDSL clan member Yuan, is praised as by western etc. developed country" the express on modern information highway". It receives deeply because of its down speed high wide, performance high-class characteristic of frequency band masses of user like , become the another kind after MODEM and ISDN brand-new more shortcut, higher effect receive the way of entering , also being most for present domestic to use receive the way of entering.

When broadband networks in Luo the process of using , can often meet some difficult problems , cause to can not get on the Internet normally , influence work, study as well as amusement. Following in ADSL wide band the process of using some common problems, offer some solution methods of reference.

Phenomenon and case study: Generally speaking, arising this kind of condition is since USB MODEM is to supply power through USB interface, just starting time to compare short, network equipment have not been had no by activation or line by ADSL MODEM i.e. the reason of activation, have not caused line by activation to be obstructed.

Solve method: Have arisen similar problem, we may wait for patiently that 30 seconds is to some minutes , and then try connection , have time as soon as start may link , and at some time, want activation for some minutes or start again may just link; If line always can not activation words, possible network links the problem that line has arisen , please prompt telephone consulting local telecommunication office, this kind of condition relative occur is more few.

Phenomenon and case study: The reason of problem and possibility appearance is many , may have following reason mainly if removing the words of hardware damage and line damage( the machine rate that this condition arises very little): First, network equipment overheat arises the condition of working instability; It is second, the voluntarily broken line in IP adjustment process; 3th and the network system of telecommunication office collapse , the machine rate that this kind of condition arises is also little, however, the author has met twice.

Solve method: If being the condition that network equipment overheat arises working instability , generally speaking, such condition equipment may join voluntarily at once; Since ADSL MODEM give out heat to measure compare still is big, hand feels to go up scald very much, for equipment, work steadily , place it in the place with better ventilation still. Is development distribution because of the IP address of ADSL, have time therefore exactly its IP will adjust , will appear to lose the condition of line suddenly, as this kind of condition, need not mind , after some seconds of clocks, may join voluntarily , if company not go up, under one, the key of RESET IO is closed , then, restart may join. If above can not solve problem , may telephone ISP that consults you , definite one takes off whether is the problem that network center has arisen.

Generally speaking, the speed of the ADSL wide band of 1 MB for our daily use( high clear video-on-demand is excepted ) or some persons make being used say , it should be enough , but time opens web page slow very much.

Phenomenon and case study: First possibility is a few of WEB servers are busy, if opening other web pages to not slow, network should have no problem , is since a few of WEB servers compare the busy and net speed caused to slow very much. Secondly, possibility is to dial the compatibility problem between software and operating system. It may be still line quality again or is to be away from problem, because what ADSL uses is telephone line , cause net speed to reduce to slow if distance will arise signal attenuation after length.

Solve method: A few of WEB servers busy is not that we can solve , suggest that it is some of that you try thereafter again. When use dials software aspect, if you use operating system of Windows XP, system dials tool from tape, it need to be not other to dial software , suggests you to use RASPPPOE to dial software if using other systems. If is line quality or distance reason, ask you to contact with related telecommunication office( visit for you to install the district department of, debug ADSL , installation reserves have contact way). Downstairs, it is that example introduces relevant installation to really reach ADSL2110-EH MODEM( lead the way from function) with use. Normally, use IP of MODEM that acquiesces in: 192.168.10.1 need to be installed the agreement of TCP / IP as customer end( each join to the machine of HUB or switching equipment) machine after guaranteeing to net card and HUB or the connection of switching equipment well as well as the agreement of IPX / SPX of local area network, then, need to install IP address 192.168.10.X, follow MODEM the region of place is the same, son nets to cover yard 255.255.255.0 , acquiesces in gateway: 192.168.10.1( the IP address of MODEM), DNS server installs local telecommunications network Luo IP address. Other choice project acquiesces in may.

If use is to really reach 5800 U as well as similar do not lead the way by USB interface ADSL MODEM of function, actually also, may share go on-line. A machine with the connection of ADSL MODEM does host computer, and as other machines, through netting twine, join to HUB or switching equipment. In which on host computer, install IP address 192.168.0.1, son nets to cover yard 255.255.255.0 , acquiesces in gateway: 192.168.0.1, DNS server the local telecommunications network of installing Luo IP address, at the same time, choice passes through local area network to share ADSL , and can not open WIN XP on host computer from the fire wall of tape, otherwise will can not get on the Internet. Hold as customer, need to want to select to pass through the go on-line of local area network may , if is the system of WINXP, do not install basically may get on the Internet , this kind of method major yes abuse makes the performance of the machine of server is on good terms somewhat, also once server barrier machine, other users can not get on the Internet.

network bandwidth as well as the net way of use mainly, present normally general ADSL speeds has 512KBPS, 1MB and 2MB mainly, Cable MODEM and the sub-district bandwidth of wide band are even 10 m, but its actual speed often depends on the service quality of supplier , has time and can not reach the speed of name marked. Generally speaking, the network of 1 m bandwidthes may to let 1-12 personal net browse, chat and daily uses such as dispatcher E-mail have no problem , all user shares the bandwidth of 1 m together, but bandwidth is not that average distribution gives each computer, if a or some of machines in which at the same time use multi-line Cheng download tool download file or play some networks of more severe occupied bandwidth to play , so will plenty of occupied bandwidthes, cause other computer net speeds to slow too , can not even glance over web page. If often arise similar condition, suggesting the user in net to use single thread download or choice to get on the Internet for density not large time download.

Solve to share net problem , have 3 kinds of method mainly: Use HUB or switching equipment, directly join to the wiring of broadband networks HUB or switching equipment goes up , then through the net card of two computers, is linked respectively with HUB or switching equipment , may share wide band through sharing software; Secondly, on the machine that has joined wide band , install a net card again , block the net of other a computer to be linked to it , share software through network to share go on-line; Again, if your fund is relatively abundant, the netting twine that may select a router of wide band and will net coherent wide band receives the WAN port in router , and then blocks two computer nets to be linked with the LAN port of router to receive, PPPOE that deploies router dials function, may let wantonly a computer independent and net.

Many friends worry about that self shares the go on-line of wide band, own machine will be been dark , actually generally speaking, now share the function of software have compared is powerful, normally, it has the function of fire wall , when outside use joins the time of local area network, because of external local area network, has only a legal IP address, external world even if connection goes up , have also joined to only that server that shares. Other internal computers can not be visited , can not be also invaded , therefore compare with every computer independent go on-line, sharing go on-line have raised the router of other, a lot of wide bands and the safety property of computer greatly, also have the function of fire wall, so, outside connection also has the very router, the most hacker attack can no more take effect after meeting router , therefore has higher safety property, because router is to not fear to attack. Therefore, all though rest assured , general you will not be gone to by " dark "! the choice of many nows, what comparison is common is that choice the on line of USB Link will two computer interconnections, then, share go on-line again. What need to pay attention however is that the line of USB Link on line has two kinds: A kind of is to have offered the most simple file only to transmit function , and need to have the aid of special software to realize , this kind of line can not realize to share network; Additionally, a kind of USB line on line is integrated into special control chip, installation afterwards in hardware list meeting fictitious is network adapter, on use and disposition, may realize basically as net card to share go on-line , is short however comparing with netting twine for its connection to be away from comparison, and price will be a little bit more expensive. Besides, the way that you may still pass through wireless go on-line , though, it is convenient, however, the price of wireless equipment is also expensive.
