Missing ethernet connection presario sr2125 uk.

Hello, I've read through many posts here and elsewhere but can't seem to find an answer to my problem so my apologies in advance if this is seeming repetitive

First of all, my PC is a Compaq Presario SR2125 UK.

I recently added memory to substitute the original 2 x 512 with cards memory 4 x 1 GB. It is the only "tinkering" I did it to make it a non tech type person. Other than that, it is like it is out of the box and several years of general household use.

My problem is that last night during a storm, we had a power failure of nature that lasts several hours and when we arrived finally be able to come back, I couldn't connect to the internet.

The PC is on a wired connection directly from the rear via an ethernet cable in the BT Home Hub. Other devices can connect wireless to the hub, and once I had found an old Belkin Wireless adapter can this pc.  Having finally got online I spent hours reading without result.

My pc is clean as a whistle according to Norton full scan and MBAM. It seems fair that my adapter has completely disappeared from the Device Manager, I checked in all the devices section hidden... everything. If my thought is that this little piece of kit got fried in the storm.  How it happened is beyond me given the "charge" should have go through the (?) surely first router, seemingly unharmed. My questions are...

How to run again? or

How can I replace it, if indeed it isreplaceable? That is, where should I look for a code of possible room or something to allow me to buy a new one, if I can

The only other thing I can think to tell you is that I tried another ethernet cable, another Jack on the back of the hub and to tell you there is always a light at the back of pc Tower, place where the ethernet cable is plugged in.

Really not sure what is relevant information that could shed light. Any help much appreciated even if it's just to tell me he didn't that can do anything!

I would like to start by erasing the BIOS settings. Don't forget to unplug the machine off before doing so. The instructions are at the bottom of page HERE

If it does not detect your ethernet, it may well have been zapped by the incident. It's a chip on the motherboard so no way to replace directly. You can add a real PCI network easily, it simply plugs into a slot in a similar way the memory. Most stores that sell computers and accessories include network cards. Just be sure to specify that you need a PCI_not the last type of PCI - E.

  • Compaq Presario SR5113: Ethernet connection problems

    I recently did a clean installation on an old PC and put XP on this machine, it did not find the driver for the ethernet connection and no matter where I'm looking, I can't get the Ethernet to work with that PC.  I get the error message about "the wizard cannot find your network hardware.  And that I must first install and configure your network cards... The network adapter is part of the motherboard.  All "network adapters" I check seem to be "working properly" according to messages.  Network adapters that are listed are:

    Direct parallel

    Miniport Wan (IP)

    Wan (IP) - of Miniport Packet Scheduler miniport

    Miniport Wan WAN (L2TP)

    Miniport WAN (PPPOE)

    Miniport Wan WAN (PPTP)

    I had to go show hidden devices to see these.  Don't know what to do and when I am looking for the drivers on the website of HP, the only rider that appears is the lightscribe update!  This isn't really the support for one of their older products.

    Clues?

  • No Ethernet connection after connection GS105 switch

    Hi all

    I have a few questions on our new bought GS105 switch. It is said that this model is a switch so that I can plug in the cables and make them communicate. However, when I connect to my laptop to pass, it shows an Ethernet connection, but when I click on this link, I can not connect. Why does this happen? What is my problem laptop OS or hardware problem or the problem of the switch? Thank you for helping me

    My goal:

    I want to connect my laptop to two USRP to communicate. However, the USRP can only support GB Ethernet and my laptop don't have 10/100 Ethernet. So that they communicate, we bought this GS105 switch and connected the USRP and portable to move (this method according to https://forums.ni.com/t5/USRP-Software-Radio/usrp-2920-can-t-connect-to-PC-WindosXP/td-p/1920379 ). If it connects successfully with each other, I can run the "uhd_find_devices" command in the Terminal and see information on the devices. However, I can't find any UHD device which means that there is a connection problem.

    The methods I've tried:

    • Connected the Ethernet cables and cables for power for several times - did not work
    • Check the lights on the switch - good times (lamps for cable USRP) and the left light on my laptop
    • Clicking on the "Wired connection" icon in my laptop, all the lights flash; However, after a while my phone showed "disconnected."
    • Tried another ASUS RT - N16 - worked

    System information:

    • OS: Ubuntu 16.04
    • : Computer laptop Ethernet Realtek Semiconductor Co., Ltd. RTL8101/2/6th PCI Express Fast/Gigabit Ethernet controller (rev 07)
    • USRP Ethernet ports: Gb Ethernet

    Problem solved because the USRP IP address is: 192.168.10.X. I can't install wired for DHCP automatic. Should I manually set the IP address and also try to avoid the collision of IP address.

  • Slow down webpage loading w/Ethernet connection

    Hello

    I have a Z580 Ideapad with an internet connection cable 30mbps (under Win8.1). I tested the modem cable with a number of laptops in my house, and the Ideapad is the only one that expires on a regular basis on the loading of Web pages.

    What I tried:

    1. Update Realtek Ethernet driver to the latest version

    2. changed to the servers DNS of Google ads (no difference in cable operators)

    3 power settings changed to High Performance (rather than the balance or the setting of the battery)

    4. disabled IPV6 on the ethernet adapter

    The problem seems to be random. Pages will load more quickly, and then suddenly they all then expire (such as google and sold). When I ping the url and the ip address, then they expire during these periods.

    The problem is definitely with the laptop and not as such cable connection. The modem has no need to be reset, the other laptops in the House of pages Web loads normally.

    Thanks for all the suggestions.

  • WiFi for computer laptop HP ENVY 15 and Ethernet connection problem

    Hi, a few months ago, I brought a HP ENVY 15 Notebook PC running windows 8.1. It is connected to my wifi with Ralink RT3290 802.11bgn Wi - Fi adapter. My modem is a Technicolour TG582n 2 Wireless ADSL + with wireless 802.11 b/g/n compatible.

    As soon as I got there I noticed a problem of internet where I would be able to connect to my home WiFi network and get full reception bars but would have a hard time to access Web sites on web browsers such as chrome, mozilla and internet explore pages takes some time to load and eventually reached a page "this webpage is not available" (for chrome). This problem seems to occur only with my home network as it can connect to public wifi and my wifi friends and yet I have many other devices such as laptops and other smartphones connected to my wifi that did not at all have poblems with internet and it just seems to be mine. When I connect via ethernet I get good connection for about 10 minutes and then I was completely cut off. However, I can upload a file via the wifi ok if I can get it to start and I can play a game online well enough but often disconnected after an hour or two.

    I checked for new updates of pilot, but they seem to be up to date and im do not manually downloading and installing one on the hp site but I tried (I did probably wrong). I ran the diagnostic function, but it cannot detect all problems. I looked around the internet as well, but still havn't found a solution.

    Also I got the laptop sent back and received a new but the same problem persisted and as I walked through the process of the person I was talking to a admitted that I had a problem like they remote limited from my laptop for a little for the access problem.

    Please help, I've had this problem for a month or two now and is really becoming a problem since I use my laptop computer for purposes of requiring home internet work.

    Thanks in advance and I hope you guys can help!

    I understand that you have a problem with your connection Wireless at home. You are able to connect with full bars but are unable to access the web.   When you're lucky hours just access the Web, you can make a download if you get started in time or play games online for one or two before again declining. You ran the diagnostic function, but no problems were. You had the phone replaced for the same issue, but the replacement has the same question.

    You know your network is an 802.11 G or 802.11n.   How do I know if my WiFi connects using 802.11n (as superuser)

    Please check this setting.

    1. Open the Device Manager
    2. Click the network adapters to expand the list
